Unfortunately, alternate history tends to attract lost-causers and racists who feel like actual history didn't go their way. They seem to be only a minority in most of our communities, at least.
This is news to me, honestly. But if there is a reason, it might have to do with things like maps and such that could fit within the guidelines of the Alternate-History group. Otherwise, I have no idea.
