I read a good run of Claremont's run on X-Men many years ago, around the time when I was in college. 2 takeways from that:
* When you binge read a monthly book in a short period of time, you get the impression that the X-Men were a bunch of serious whiners, as in pretty much every issue, someone (in my memory, Rogue played this role more than the others) decries the fact that they're a group that the world "hates and fears." But of course, in those times, before collections were a regular thing, *every* issue was someone's first, and Claremont was just outlining what the book was about for the new readers.
• Yes, it was all about prejudice. And that SO MANY PEOPLE do not understand that explains why some writers have chosen to make the message more explicit in their books. But I guess there are some people that are never going to be open to the message in the books that they claim to enjoy.
