Wait. So not calling folks by their names is racist?

Bruh, cats in the joint will do that shit. Let's cut the shit. I know what not calling someone by their name means. I know what it means to call a person their first name instead of using a title. I know what it means to shorten a name.
But how is it a racist term? Because it comes from a racist? That just won't cut it. Period.
If he had just said 'dumb ass or crazy' would those now be a racist term? There are plenty of terms used to belittle, now they will be labeled racist? Come on man.
He was wrong, but come on man.
