It seems like this is a very important conversation for Western socialists but I really don't see much discussion regarding this. What seems intuitive to me is that the answer is probably not many, but maybe that's just owe to the crumbs we have living in the imperial core.
Thoughts?
In my experience, a lot of white Americans are really irredeemably racist. I would say this is deeply intertwined with white petit bourgeoise ideology, which is really dominant among most white Americans. Working class white Americans might be more easily swayed, especially because they are much more likely to live in the same places as black and brown people, work in the same places, etc. But the pressure of revolutionary conditions will be more acute in these areas, which will mean racist/fascist organization will be targeted towards white workers there.
I disagree, working class whites are just as racist as petite bourgeoisie. I've met a few people who worked their ass off and supported their metalworking union and then two seconds later rant about how they want to dump all black people off a cliff.
