"It's always better in memory." "...The realities of the present materially affect the perceptions of all that came before."
- Chris Claremont
These words are from Claremont's introduction to the The Uncanny X-Men Masterworks collection. Most telling I think in these and his further comments is the absence of any reference to the X-men as a metaphor to the Civil Rights Movement let alone, Dr. King or Malcom X. In fact, Mr. Claremont's comments, like his X-men were virtually devoid of color.
1963, obviously the Civil Rights Movement was often front page news of which Stan and all of Marvel were undoubtedly aware. Yet, understanding now the importance of that time and the efforts of MLK and MX it is understandable that some might retrospectively associate them to Stan's "X" inspiration. However, if you consider the uncertainty of things at that time, the stories of MLK and MX were not yet written and Stan was engaged in building Marvel, creating more characters and stories to sell to a predominantly white audience, it is hard to believe that the allegory between the Movement and the X-men (and there is an allegory) was much more than a coincidence, perhaps marginally inspired by the times in general but more likely inspired by the creators own cultural experiences and concerns.
Nonetheless, I believe there could be a value in the allegory. I once had a freshman course where I presented a case against Institutional racism and I had a colleague of mine come in to present statistics and data from his research to the class. The white males in the class could not accept the data on employment, education and real estate inequity and were very critical of my colleague's take whereas the black males and all the females were much more receptive. My colleague who is brilliant also happens to be white yet the white freshman males could not relate to the real life story he was telling. To them our society was now a level playing field for all. From their frame of reference cries of racial bias were more or less sour grapes.
I don't know if any of these students read X-men so I can't present any quantitative conclusion here but I do believe that comics as a medium can help expose people to ideas that may sensitize them, consciously/subconsciously to the struggles of those from other cultures, backgrounds, orientations. As Redjack astutely noted you cannot substitute Professor X for Dr. King nor Magneto for Malcom X, but if drawing comparisons causes people to look up, read about, educate themselves on real life stories of struggle or even fosters a greater appreciation of individual differences, therein is value.
My two cents.
Peace,
