What Would Mohammed Do?

It's tough to be Muslim these days. Never mind that the Islamic culture spawned the Taj Majal, beautiful poetry and the mathematical concept of zero; many Muslims feel that their fellow Americans now look at them sideways, as if they might whip out a roadside bomb.

To most Muslims, none of this is particularly funny. But a few have chosen to laugh anyway. Take the Muslims who run "Funny Muslim Clothes," specializing in self-deprecating T-shirts. One says "I'm not a terrorist, I just look like one." Another says "Detain me, I'm Arab."

Are these shirts funny? Politically incorrect? Sad? All of the above?
