Ask Rachel Dolezal. Regardless of how much one embraces the leftist agenda, becoming trans-black is cultural appropriation and racist, akin to an Armenian distilling tequila or an Englishman cooking chitterlings. In fact, I think just spelling it "chitterlings" is racist when the culturally appropriate pronunciation,"chitlins" has become the commonly-accepted spelling.

One would think, considering one can reject one's gender at birth, one could do the same with one's race, but alas, one would be mistaken. And REALLY racist.
