"I don't have a problem with Sarah Silverman using that joke simply because it does dig as something deeper in the thinking of the audience.I may think she's a reallt shitty comic,but anything that can bring out biases in people is at least worthwhile."

But does it? The only difference is that she has a liberal audience who says, "Oh she doesn't mean it, she's pointing out the flaws in the world." Everyone pats themselves on the back and says, "I know what she is making fun of. Ooh that racism is so wrong." She doesn't dig any deeper into their own biases.

Essentially, she is the 'Crash' of stand-up comics.
