I don't know what you folk's fixation on "warhammer fans disliking chimera squad", i highly doubt it's because any significant population actually hates aliens or wants to play imperium or whatever.

Xcom IS NOT warhammer
neither is starwars or startrek and if they have any interest in some of the larger pop culture universes, if there are people who sit there thinking that all the twileks need to die or whatever they'd be few and far between. you've also clearly not met any of these people and they likely don't exist.

Yeah, I've seen a frightening number of comments on various sites that are unironically quoting 40k while often talking about the game going "woke."
