See, I can understand and see the charges of racism. Not so much with Martha as a character (she kicked ass) but with a whole bunch of little things that add up. Mickey being a cowering little simp, Billy being essentially killed off when he dares to flirt with a white woman, Martha's family as servants. I think the problem we're running into here is the lack of explanation. While in HN/FoB the fact that Martha was stuck being a maid was actually addressed, the rest of the incidents were just...there, or dismissed. Why would the Master, of all individuals, be a racist? He wants to dominate everyone. And while I don't buy him as a woman-abuser either, at least Lucy got to shoot him.
