You cannot be serious!?! In what universe is calling someone a "left-wing radical" an example of "blatantly racist behavior?" Especially if someone is, IN FACT a left-wing radical? This, my friends, is what they call a classic category mistake. Leftness is one thing and blackness is another and there is no necessary and essential connection between the two. To say that there is, is to deny black people the key human quality of free will, which is itself a very racist position to take.
