I go completely cosplay in those worlds, hell yeah, xenophobia is part of the lore and it's fun to flip your usual behavior to let off some steam in a safe and gratifying way. I'll play the "Xeno-Scum!" screaming commissar as well as the medieval knight who thinks black people are naturally inferior. But every fucking time, there's some asshole in the fandom whose damaged brain thinks this somehow translates into acceptable behavior IRL.
No dude! How do the huge black, red and straight out Antifa-Flag hanging in the playroom, the dozens of stickers everywhere showing a fist destroying a swastika and the fotos from demonstrations showing us with the local democratic-socialist youth not give it away? Our clubhouse is not a safe place for fascists to be in!
