I'm sorry but does robin quivers not seem like an uncle tom?

I stopped listening to the stern show because it discredits the black intellect and I have no problem , the show has funny segments ,but I'm wondering would you perceive robin as an uncle tom? I mean I understand she had a rough childhood, but she has a habit of laughing at jokes even uncle rufus from the boondocks would stop to think about....just wondering what you think about her..she seems like a smart person so I am not discrediting her....
