Perhaps some of us wring our hands in despair. Perhaps others say, "We ain't gonna put up with this crap and take action to make sure that no more of these bastards enter this country.
What action can you take?
Well good luck with that. But what are you going to do with those that are already here or those who convert (lke the black Muslims in Prison)? All the Wahibis have to do is shift their support to assets already in place. Destroying radicalism in Islam is going to be difficult, but it is probably our only real option.
