I don’t think they hate black and trans people but whatever warped version of black and trans people that they have been told. There have been studies that show having a gay friend in real life make people more accepting and I assume that similar things could be shown for trans and black people.
Yeah, but when they won’t make that friend, that “fun fact” doesn’t help anyone. So they are, for all intents and purposes, de facto racist even if in a perfect world where we all hang out on Sesame Street they wouldn’t be.
The culture war is the only lever the GOP has to win elections. Their domestic/economic policy is so bad for the majority of Americans if not packaged with propaganda.
