The success [of the X-Men], I think, is for two reasons. The first is that, creatively, the book was close to perfect ... but the other reason is that it was a book about being different in a culture where, for the first time in the West, being different wasn't just accepted, but was also fashionable. I don't think it's a coincidence that gay rights, black rights, the empowerment of women and political correctness all happened over those twenty years and a book about outsiders trying to be accepted was almost the poster-boy for this era in American culture.
