I think the problem the Recast crowd faces is that the Gators are also being lumped in there too. Which leads to the movement being attacked by both sides, something the no recast side doesn't to worry about.
Another thing is that yes your right, anytime people say they want Tchalla to continue it's met with "What's wrong with a woman taking over? You must hate women'!!!" While casually ignoring that the female cast is heavily stacked and the male cast is all but gutted.
When it's countered with T'Challa has existed for 55 year's and deserves to have his story told before someone else takes over, the counters are "You must be intimidated by women and can't stand to see Black women shine" (someone actually tried this on me) and it's utterly ridiculous. Ultimately the recast crowd has Chad's word's and his families on our side and the anti Recast crowd doesn't really have a counter for that, and if you press them on it, turns out they will say some pretty damning stuff that completely undoes whatever argument they were building.
Plenty have basically said they don't give a isht about what Chad's family has said or Chad's word's were taken out fo context and Marvel is free to do as they please and they are honoring Chad and the cast and crew know better in honoring Chad because they worked with him.
Another one I see is that supes guy on Twitter made a comment about Shuri needing training and people tried to dogpile saying it was misogynistic and that she is a fighter because she fought Erik and Thanos army, and claim we don't know how good T'Challa is because we never saw him train And how it's a double standard.
They can't counter with actual facts or anything they make up their own head canon and believe it to be the truth.theybare hellbent on believing T'Challa MUST die so they can saw goodbye and ignore how that will effect young black kids and to Recast is disrespectful to Chads memory (and also hurts their immersion because fans apparently need to be spoonfed why Tchalla would look different and needs an in universe explanation).
Yet at the end, all of their excuses and reasons rely on ignoring what Chad has said in life and what his family has said, and so they have to attack the movement itself and throw out accusations of misogyny to counter.
"Gators" is a good term. I don't think lumping the Gators in with more benign recasters can be avoided. That's the go-to move for basically any disagreement that happens in geekdom now. And that's not to say there isn't some truth in many of these geek dustups that there are some people who often spew racist, misogynistic, homophobic, transphobic, xenophobic, and other -isms and phobias sentiments. However, that also provides a too convenient paint brush for corporations and "real" fans to use to dismiss any disagreement or complaints.
When hurling the isms/phobias doesn't work, they can also call people crybabies or say they are whining or go for some extreme example if not outright misstate or misconstrue what they say the other side wants in an effort to delegitimize (supposedly) the stances they disagree with. So, there's a lot of bad faith actors here, but the mainstream media is so one-sided they are on the lookout for those who might complain, but never the side that is attempting to silence or police discussion. Misandry isn't a word that exists in the mainstream.
I personally don't think there's anything wrong with feeling that they need to depict Shuri leveling up to take on Namor. I don't think it would do well to have him get handled decisively by Shuri in his MCU debut, without seeing her leveling up in some way to take him on. Letitia Wright is very petite and her portrayal in the first film didn't set her up well to be taken seriously as a BP successor, yet. And that was fine, because it wasn't intended to be. However, for her to take on the mantle now, I do think we need to see her bulk up, etc. to sell her beating Namor. I'm assuming here that the MCU Namor will have been a hardened warrior by the time of Wakanda Forever. I don't think that's necessarily sexist on the face of it to raise the question. And while we didn't see T'Challa prepare, Boseman was a bigger, more muscular person that right off sold that he could handle himself. Plus we saw what he could do in Civil War before his own film. Shuri's fighting wasn't as impressive in Black Panther and I can't recall what she did in Infinity War, so it will stretch credulity. And with Namor there will be a new audience to cater/answer to, and that will be Latino fans who will want him put in a very good light. And I doubt the anti-recast crowd will go ham too much on Latinos if more speak up about wanting Namor and his people to not get punked out.
With what Namor as a character means to Marvel overall, and then Disney wanting to appeal to the Latino market, don't be surprised if they don't DoomWar Wakanda Forever, and it's a stealth Namor film.
