Something you can do is tell @TeamYouTube that you stand with the BlackTruth, and want ProfBlackHQ reinstated. Tell them you recognize YouTube is hostile (perhaps illegally so) to any views they don't personally agree with and censor users behind the false claim of "hate speech."
The fact that you have had the gall to classify the professor's channel as hate speech proves that you have white supremacists at the core of your organisation. You are disgusting and the non reinstatement of this gentleman's channel is an act of racial aggression and suppression
