As a confirmed video watcher, hexbear's one and only, another pretty goated take from F.D.in regards to how white leftists (in actuality) and "leftists"(libs) are pretty poor at race relations and often quite literally trigger black folks in argumentation and rhetoric by madlibbing electoral candidates and movements with the same sentences otherwised used by blatant racist reactionaries. Summary for non-readers (read fellow Amerikkkans) over.
Mandami, from what I've seen, is smarter than this (maybe some of y'all should be forced to take Africana studies courses as part of re-education?), and my skepticism of him is funny for a bunch of other reasons. White leftists and liberals (collectively) are notoriously bad at navigating black skepticism, but frankly, at this point, I am of the belief that in the context of the U.S., that is gonna have to be a family issue (read black) to resolve internally, especially since the liberal brain worms seem to have successfully infiltrated us as a group.
It is why I sympathize with a lot of the non-US members who get irritated at us calling them doomers in regards to our revolutionary potential (generally talking US-Canada, but vaguely western countries all kinda apply). A lot of rebuttals I've seen towards them give the same chauvinist vibes I often see non-black leftists come into black-spaces with, which is coupled with anger at... well-earned skepticism?
Anyway, the soapbox under me is creaking, and my feet hurt. 
Edit: Steps back on soapbox, I do think there is a bit too much grace for a lot of Black elders as well as a bit too much faith in electoralism, but that comes with F.D. I think he is technically right about the low information voter comment he made (how leftists really need to be careful in how they use it in black spaces), but I feel he implies that it isn't true when in my experience it generally is, but wtv, I'm just pre-empting some potential arguments I don't care for.
