Is the Boondocks TV show contradictory?

Now, don't get me wrong I love this show, it is super leftist (which isn't a problem) and sometimes exaggerated but I learned alot. But one thing that I noticed is that whenever they show someone that they consider ghetto or ugly they are always dark with African features i.e thick lipped and wide nosed (think Uncle Ruckus, Colonel Stinkmeaner and the background characters in the Gangsterlicious episode and the Free R. Kelly episode, i.e the big fat black women) opposed to thin lips and pointy nosed . Even for all of Huey's condemnation of the white supremacists power structure it seems the writers behind the show and/or Aaron McGruder seems to buy into all this light skinned white featured look. Why are their family and Tom DuBoise light skinned with white features and are the 'good guys' on the show? and why are the black women on the show that are 'pretty' are considered light skinned? Why aren't they showing the variety of black people and representing us? Why aren't there dark skinned pretty women as well as men who aren't ghetto? I know its just a TV show but you have to be aware of what your watching and taking in. I really don't want to stop watching it, but why is this? Did anybody else notice this? Can we write to them and make them stop? Are they doing this as a way of reaching a broader audience? Its still sellin out. That sh@# doesn't fly with me.
