Let's take this one slowly, point by point.
1. Everyone in Los Angeles is black.Everybody knows that if you spell out a word instead of saying it, children and the simpleminded won't understand what you mean. Lesnar just wants to let the racially pure know that he's got their backs without tipping off the mud people.
2. Ditto pre-Katrina New Orleans.
3. All black people live in desperate poverty.
4. People living in desperate poverty are subhuman.
5. As subhuman leech-rat-ape things, they cannot control their lizard brains.
6. The solution is preemptive lynching.
