It is surprising how deep this goes.  I have student who is into debate and forensics.  In fact he goes to regional competitions.  I overheard him one day saying that he has a tactic where he implied, says, or asks if his opponent is a racist.  Throws them off their game.  Later, I asked him whether or not that tactic was underhanded as you could sucessfully brand someone a racist outside the debate?  He didn't care so I asked him what would he do if his opponent doesn't not even care or reacts to the smear.  He said that had never happened.
 
That is from a college educated young black man who wears a suit.  Who knows where he will go in the future;
