That's not true I like both Roseanne and Gunn. I also like Mel Gibson, Bryan Singer as well as various other lefties and righties.
People keep trying to simplify the current state of political correctness into left or right but the truth it a far more complex than that and the lazy label throwing actually makes it worse. I really do hate identity politics, it just avoids actual discussions in favor of going left or right for the sake of it.
