FiveThirtyEight has an interesting graphic about which groups Democrats and Republicans think face "a lot of discrimination."
Democrats, as one might expect, tend to think that groups who face a lot of discrimination face a lot of discrimination, and groups who don't, don't. Republicans, by contrast, are oddly "egalitarian" in their beliefs. Yes, Christians are on top, because, you know, Republicans, but there isn't a huge gap between them and the rest of the pack. Eyeballing it, virtually all groups clock in between 40-50%.
With one glaring exception. Republicans seem willing to believe that a trans person has it as hard as a Christian or a Muslim is about as likely to face discrimination as the ever-oppressed White. But if there's one thing they're damn sure of, it's that Black people are made in the shade here in the US.
