A few things:
1) The Storm/Black Panther marriage was rushed. It came way out from left field. The two of them should have gotten to know each other as ADULTS better over the period of at least a year. The whole business about EJD butchering Storm's character his "Storm" mini stands as proof of that. To accept that mini as part of a build up to an Ororo/T'challa marriage isn't going to fly as the only real thing it accomplished was devaluing Storm's character. It alienated Storm's fanbase...and with good reason. It only served to turn people who really know and love the character, Ororo, against the marriage. As far as I'm concerned, that was an alternate reality Storm EJD wrote there.
But here's the thing.
I'm yet to read of a single Black panther fan who endorsed or accepted EJD's mini series or the retcon that it embodied so the real question that should be asked as to why said retconwas authorized should really have been addressed towards Marvel Editorial themselves as opposed to segments of X-fandom accusing Reginald Hudlin of being a racist just because he married two of the 616 MU's most prominent African characters.
Your repeatedly harping on about the EJD Storm mini as if it's the primary catalyst that's sustained the hatred aimed at T'Challa even post AvX doesn't even begin to justify the level of lunatic vitriol that Mr hudlin has had aimed in his direction for years post his writing of the Black Panther solo book and it definitely doesn't justify the online trolling and abuse that BP enthusiasts have had to put up with on forums like CBR in particular and other similarly themed forums in general.
EJD's Storm mini is just the convenient excuse some like to pose as their primary reason for not supporting the union between these two magnificent characters so let's not mince words here.
2) Storm was very much the unreachable goddess. Its not her fault if Dr. Doom, Dracula and Loki were in awe of her and wanted her for themselves as a lover. As you can see, she didn't end up with either of them. In fact, she told Loki off. You can't fault those men for having good taste in women. 

As evidenced in the scan above, Ororo was never a "goddess" by any stretch of the imagination.
According to Charles Xavier, Ororo was merely a mutant who he expected to leave behind her "fantasy" life in Africa where she was revered and appreciated by the people there, to join him on a journey to the USA, where she'd be expected to lend her powers to the defense of a world that "feared and hated mutants."
Thus began Ororo's following the lead of others who seemed to think that they knew what was best for her and it's a trend that's continued all the way to the present day where Storm is portrayed in the X-books as someone who can't make any decisions without referring to the counsel of others.
The fact that the same fans who claimed to have a problem with T'Challa and Ororo being married still celebrate "what might have been" when characters like Doom and Dracula were in the frame says a lot to me about where some of these fans true alliegance lies in more ways than one but at the end of the day, it doesn't really matter because it's pretty clear to all but the willingly deluded that Marvel Editorial really messed up when they allowed former X-Office editor, Nick Lowe to run the X-franchise into the ground with his divisively mean spirited and short sighted agenda.
3) I recall John Byrne stating on a message board (IIRC) or an interview that as far as he was concerned, Storm's and BP
s relationship ended as children. He stated that Storm was too good of a character to be in a relationship with BP, though he felt they could be friends. I vaguely remember this. That may be why nothing was explored further.
What?
You mean the same notoriously racist John Byrne?
Why would any self respecting comic book enthusiast take him seriously or even give any credence to his opinion?
Byrne's statements as to whatever relationship T'Challa and Ororo had (past, present and future) is manifestly irrelevant for the purpose of this discussion.
However, since a number of your posts on this forum have pointed to your stated belief that being paired with T'Challa "devalues" Ororo as a character it comes as no suprise to me that you'd quote John Byrne as some sort of support to your argument without seeing the irony in Byrne's racism as a possible influence on his opinion of T'Challa as a character of substance.
That said, I'm going to defend Claremont, here. When he came on board to write the X-Men, the second generation team was already put together. He did not write Giant-Sized X-Men #1. It was an international team of mutants, so they had one from Africa, one from Ireland, one from Germany, and one from Canada with Cyclops leading the team.
I'm sure the irony of the fact that Storm was the only mutant of African descent on a team that was (at the time) 99%
ALL WHITE is totally lost on you.
During his run on X-Treme X-Men, Claremont took over the writing of Bishop. I remember him stating on a message board that he felt Bishop could join the ranks of the premier X-Men like Storm and Wolverine with the right development. He sought to move Bishop in that direction. He made him like a cop, boosted his telepathic defenses to such an extent that his mental defenses were second only to Storm's and Sage's on the team. He also gave Bishop a power boost by adding on new dimensions to Bishop's powers. Originally, Bishop could only absorb energy and throw it back at you as an energy blast. When CC got ahold of him, he enabled Bishop to use the energy to increase his physical strength, stamina and reaction speed. He also tried to establish Bishop as being one of the most formidable X-Men/mutants around. He established that since Bishop was from the future, he's had the opportunity to study the mutants in the present to learn of their battle strengths and weaknesses and to be able to take advantage of those weaknesses to use against them in battle. Claremont tends to write women and characters of color as premier characters. Characters of color were never just tokens under CC's pen.
None of which changes the fact that post Chris Claremont, the X-books are still bereft of any non-white characters in positions of authority or meaninful leadership roles. (especially Black male mutants)
Where is Bishop now?
4) It was not that CC could not be bothered by giving Storm a relationship interest that stopped him from giving her a BF for years, it was just a part of her character. Not only was she very much the unreachable goddess, this is a woman who also kept her emotions in check for fear of affecting weather patterns as they echo her emotions. The whole unreachable goddess thing played hand-in-hand with her keeping her emotions on a tight leash for fear of causing damage. It is my assertion that keeping her single played on that dynamic.
And that's a supposition (on your part) that hasn't exactly been borne out to any real meaningful effect or impact within the 616 MU.
Has Thor ever exhibited any problems controlling the weather when in the throes of passion? But then, I suppose that as an actual mythological deity as opposed to a mere mortal plasking make believe "goddess" he actually has more of a handle on things of this nature than the Windrider would.
Me:
I agree that it would have been both in-character AND mature for both Storm and Black Panther to take some time out to reflect over what happened during AvX, however, keeping the two as a married couple would have been a BAD idea. It alienated too much of the readership.
Keeping both characters married only alienated readers, writers and editors who were biased against the union of both characters right from day one so citing this supposedly alienated readership is quite disingenuous to say the least.
You may not realise this yourself, but based on conversations that I've had with many a BP enthusiast posting both here as well as on CBR a lot of us where Storm enthusiasts as well long before her link to T'Challa was revisited first by Priest and then Reginald Hudlin so I personally find this continual reference to Storm's X-fanbase as being the only one in existance that matters, exceedingly disrespectful but fully to be expected from a fanbase that actively supports and endorses active discrimination against anyone whom they percieve as not being sufficiently submissive to the X-Agenda.
As I've stated time and again, too much damage was done to Storm's character at the beginning of the whole ordeal (going all the way back to that HORRIBLE mini) to prop up BP and the marriage thing that sent her fanbase running for the hills.
And I stay refuting this assertion of yours because I'm yet to see where one writers misstep supported by editorial falling aslep at the wheel, justifies the wholesale vitriol that was (and still is) aimed at a writer who had nothing to do with EJD's mini series.
Christopher revisited the relationship during his tenure as BP scribe but was not allowed to develop it further by the selfsame Marvel Editorial who acquiesced to Mr Hudlin's proposed storyline to revisit what Priest (and Claremont before both of them) had touched upon so to continuously push this false "EJD was to blame for my hatred of BP & Storm as married couple" meme as something worthy of recognition and support really renders your argument null and void.
No one else uses such a hackneyed argument to opt out of reading about characters but I've come to accept the fact that some X-readers live in an alternate reality where common sense and a balanced appreciation for nuance in well written stories are rarely appreciated as long as their favored character gets to strike a pose and shoot directed lightning bolts at her former husband or talk smack about him in general.
They were never going to come back and they were very loudmouth about their resentment of the union. I think the two characters should have remained good friends, though. Also, I feel the break up happened in a way that was unseemly and unbefitting of either character. It was beneath the dignity of both characters.
And I say good riddance to such fickle readers who use triviliaties to cloud the true nature of the divisive and bigoted nature because let's face it, a lot of the hatred that the marriage of T'Challa and Ororo generated amongst some of these readers was purely racist in nature.
It's just unfortunate that some of the Black readership who joined the bandwagon were (and still are) blinded to this reality on some straight up Stockholm Syndrome ish.
T'Challa and Wakanda are being portrayed with the dignity that should always have been their portion in the 616 MU if not for the deconstructionist efforts to destroy both concepts by the likes of Jonathan Maberry via Doomwar and every single X-writer who disrespected the marriage during Reginald Hudlin's BP run all the way through to AvX and beyond.
So for the time being, most BP enthusiasts will continue to watch events as they develop in the hope that Ororo is given a true opportunity to grow as a character after having been devalued by the very office that claimed to have such "Big Plans" for her post AvX.
