The race card has LONG since been overplayed. “Racist” is now no longer a stinging epithet it once was, its meaning diluted and misused to the point of banality. It has become an instrument of projection, asserting that the “enemy” is doing something or behaving in a way that is indistinguishable from what the accuser himself is doing. And therefore, it has no meaning - “I know you are, but what am I?”
Considered to be a playground taunt.
How about using the old Pee Wee Herman tactic? When called a racist say, “I know you are, but what am I?” Say it every time they call you a racist - they have no answer for this. However, I would expect them to get quite angry over this response, so violence may ensue.
