"multiple visual parallels" my arse! I've shown you have to present some real evidence of heritage, not some kind of amorphous "parallel", and it's just not there. It's your own prejudice which is showing. Prejudice is making up your mind about something and applying it blindly to all cases without investigating or showing any knowledge. It is offensive: you would be equally pissed if I were to come up to you and call you racist simply because you're white and the blackface minstrels were white. But that's not something I've done or will do, because I'd have no case, it's something you did, and perhaps it's time for the soft analogists to start to show some contrition and apologise. They've had a chance to prove their case and have failed.
