Literally all the ppl I've seen complain about white veganism or privileged vegans have been white. Like I'm sure there are plenty of POC making this claim, and as a white person I'll sit and listen, but it feels overly silly for white carnists to make this.
I can't stop repeating the claim that all the research I've seen shows that lower income people are more likely to go vegan, and rich people are less likely. Posh people are going to be more selfish. In my experience they don't stick with veganism as well, and it's more often tied to a short-term health fad.
Edit: I forgot the "black people are 3 times more likely to be vegan" headline. I think it says a lot that marginalised groups go vegan faster than the dominant social groups do.
