Dick Gregory comes to mind.
Mae Brussell in one of her radio shows (which I cant find) described why there were so many Jewish JFK assassination researchers. She described her own research awakening, the CIA bringing Gen. Reinhard Gehlen over to USA after the war, as the starting point for her JFK assassination study. She claims to have plotted the time-line of the rise of nazism in USA right up to 'the big event'. That JFK's assassination was the takeover of these nazi forces. And apparently, she wasn't alone, that many of the 1st generation JFK researchers who were Jewish used to regularly meet up, she learned they had also paying close attention to ex nazis given key roles in USA's military/political infrastructure. These early Jewish researchers had come to the same conclusion as Mae Brussell -- the assassination of JFK was a nazism takeover.
I would imagine most black folks in USA had long before concluded USA had become like a nazi hell hole. What will be, will be.
