Are you saying that there has never been a racist culture that wasn't capitalist? Or are you claiming that capitalism anywhere in the world creates racism everywhere?
Both are pretty bold claims that would need evidence to support them. But like you said, prove it, I dare you.
Because racism doesn't coincide with an economic or government ideology. If that were the case, then AOC, Kamala Harris, or Ihlan Omar (and more) wouldn't hold office. The idea that Angela Davis expressed is now outdated
Do you know anything about her work? Her analysis is still accurate. Most intersectional class based analyses will be true regardless of function. Women of color in politics doesn't disprove wealth based systemic inequality.
I didn't give those examples because they are women. That's a completely different topic. And poverty doesn't care what color your skin is. That is my point.
And Angela Davis is a far-left activist that has worked with the USA communist party and The Black Panthers. She was a philosophy professor and she is very well educated. Also, somehow firearms that she purchased fell into the arms of a 17 year old so he could take hostages at his brother's trial. Ultimately the judge, the brothers, and another defendent were killed during a shootout with police.
You can't have capitalism without a class of wage slaves. It's arbitrary that America uses race to differentiate. It could've been brown haired people, or women, instead.
I haven't read her work, so I can't comment on the second part. I'm curious if you know what her response to the above would be?
