I think by “black-skinned Uncle Tom race traitors” he means the guys at SPLC. That probably got their goat.
Blacks have little emotional use for white liberal elites like the kind that started the Southern Poverty Law Center (Unitarians - uber nose-in-the-air types).
Angry blacks prop up the white liberal elite power structure but it's not an easy truce... but I can see where it could lead to the type of comments about whites (liberal elite whites) attempting to make black men gay - which might have some truth to it... but it's not the most important issue for white liberal elites...
White liberal elites want blacks angry, dependent and compliant. And willing to vote that way... They don't want their black opinions on anything beyond race issues.
I'm pretty sure he means black conservatives like yours truly. Guys like him hate guys like me even worse than they hate whites.
