Oh dear, you don't have a problem with female space marines? Neither do I, even though I'm willing to acknowledge that goes against the lore... well, the current lore, anyway, since 40K's fluff is wildly inconsistent. I may have to watch myself, but then, I'm Necron player, so why should I care?

I can certainly sympathise with the idea that people see what they want to. False dichotomies make it easier to dehumanise the "other." Communists see me as a science-denying creationist, and creationists see me as a godless communist, even though neither of those things are true (well, the "godless" part is true). It gets wearisome after a while.
