I would send him an invitation to the next Tournament located in Patrick's basement with a request he must paint himself black to participate in the competition and let it sort itself out.
Shao Kahn's one of 'em! After all, he's currently voiced by Ike Amadi. So he'd fit in the Tournament in a T. Oh, and Jax too. I don't care about that Gay-ras nigger, he's already decimated in the niggeroni grinder amongst with hundreds of dead niglets hanged like he does with the Tarkatan mutants in the Flesh Pits. Raiden and Fujin's too white to be assumed as a nigger, and I guess they'll have a life-of-an-opportunity gawking at the Tournament in amusement.
