I look at it like this. Grim Bastards, the Niners, SOA, and the Mayans only work with each other so they can get money. Black hates white, white hates black, but everyone loves green.
I can't think of another program that have characters that look SOA, talk like SOA, or as real as SOA.
The racism bit doesn't bother me too much. The killing doesn't bother me either. The heinous crimes they commit doesn't bother me. They're a biker gang. I expect them to be foul human beings. If I wanted some cookie cutter garbage, I'd watch True Blood or Glee.
Waiting for that Grim Bastards spin off on BET.
