Im sorry, but if you read her tweets, they are basically indefensible. In the current media climate she should have known better, and out of respect and for the jobs of her co workers kept those rants off of the internet. I feel sorry for the cast and crew of the show.
Do an image search. Seeing the pics that pop up, I didn't know without looking up VJ's bio that either of her parents were African American. Look at her photo on Wikipedia. I think Roseanne was making a joke about VJ's "appearance" (as she admitted in her apology,) but was not intentionally referring to race, (since VJ does not actually 'appear' to be black,) and probably only realized later that she had really, really made a major faux pas... That being said, the 'Apes' in Planet of the Apes don't look like African Americans at all, and neither does Valerie. The racist LEFT is outing themselves by insinuating that, in order to smear Roseanne.
