Actually, I have heard a few muslim Americans say something along the lines of "just wait till we take over America."
It is okay for muslims to go to other countries but they are killing non-muslims through genocide in their muslim countries.
Of course, the muslims will come in with their children and carry out the genocide. Let's not forget the christmas tree bomber (

The even more pathetic thing is that the people who quote statistics will say that some americans are terrorists without adding that they are offspring of muslims. All part of the muslim strategy to commit genocide while denying the obvious link between these evils and Islam.
