So should black comedians be jailed for their jokes when they generalize about other groups? Should Dave Chapelle be in prison for making jokes about white people, since that's what you're implying?

Racism is defined as prejudice, discrimination, or antagonism directed against someone of a different race based on the belief that one's own race is superior.

What these kids did was not racist.

First of all, where did I say anything about prison?

Second, this was clearly antagonism directed against someone of a different race, and is therefore racist.

Antagonism is hostility. You're actually the one who even mentioned this being black humor, so this can't be antagonism if we both agree these are jokes. Trying to make people laugh using taboo subjects is not antagonism.

As for prison, I'm implying what consequences you would assume for individuals who would be so vocal about what you would call their racist acts.
