I never complained about the first season having no Black characters. She white, from a white neighborhood, went to a white school. The last thing I need her to do is crop a Black character on there for 'diversity.' And thanks to everybody's complaining what did she do? Crop a Black character in the cast for diversity.
She can't win even when she tried, because now everybody's complaining because he an awkward elephant in the room.
When complaints about the first season arouse Lena said something along the lines of not having Black friends in real life to add them in her show. It would have been admirable if she stuck to her guns.
Either way I'm not tuning in, there's great shows (mostly on the Web) I can relate too. If we put as much energy in exposing them, than we do exposing Lena's lack of Black characters we'd show alternative Blacks (those uninterested in BBW, RHOA and everything other acronym) watch TV too.
