I wonder if anyone would defend me if I said Whites > Blacks, and supported it with an argument like your professor did (jokingly, apparently, but still).
right?
but something that really bugs me is the fact that he received trouble for saying Blacks > everything else(through he never said something like that) instead of all the jokes and words he used afterwards.
Except he did. Even if the claim is a benefit to one, saying something like one race is faster than all others is racism. If you don't like it take it up with a dictionary. If your white teacher had said white people would survive because they were smarter at rationing supplies than blacks and Asians bet he would be in trouble.
