In any case, organized structures of black racists exist and conduct their structured work.
You seem to consistently confuse "systematic" with "formal organizations". That's completely missing the point about what systemic racism is or, for that matter, what a system is. If you can understand that the economy is a system that compels the exploitation of workers, then you should be able to understand racism as structural/systemic. Otherwise, we may as well reduce class struggle to individual bosses being mean to individual workers. If you do not get this pretty fundamental difference you will forever be mired in liberal politics.
Yes, my friends, the Jews, worked with the black proletarians in NY, and claim that many of them are racist. I'm not saying everyone or most, but many are.
Is there any news for you? Many of the whites I worked with in Israel or Russia were racist or ethno-nationalist, but the same can be said about the colors workers (or haw do you call them) I worked with. Racism and nationalism are typical for a large number of workers of all nationalities. And I'm extremely surprised that you're surprised.
