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."
@TeamYouTube we are listeners of @ProfBlacktruth. You took down his page stating it’s hate speech. We would like to know what’s your definition of hate speech? We did not hear anything hateful said. So what is @YouTube ?
