Americans actually could care less if anything here gets insulted.
I live in SC. They still hate and vilify Lincoln here, so that doesn't hold up.
We mock all our leaders. We mock God - hey look at PK, a leading proponent of God mocking and he's not alone.
In fact, the wonderful prophet Mohammad was a piece of garbage child molestor - the GREAT Pedophile of his time. It is a religion of hate. And enough nonsense about it's just the radical Islamists. It's the whole thing. The ones who don't go wild are mostly in civilized places where they'd get arrested.
These riots are just another anti American excuse. The more Moslems that kill each other in the Middle East, the better. It's a good thing.
