Racists. Who do they think their ancestors were? White guys? We ALL came from Africa originally. Insult black people and you are insulting your own ancestors and therefore the sperm and eggs that ended up creating you. So you are insulting yourself and thus insulting everything about yourself, including your opinions, including your racist opinions. You are, in effect, cancelling out your own views. Racists are not only idiots but self-contradictory paradoxical idiots!
