THe supporters of this deal are not supporting Radical Islam. In fact we are in large part supporting a tool that will help in its destruction. Its the "lets declare war on Islam" folks that have the same goals as Bin Laden. Not saying you support his terrorism but he too wants this war.
You are right in your point. If we can't differeniate between the two (the political perversion of religion and the billion or so normal Muslims) all can spiral out of control - as humans often regrettably do - with hatred fueled by bigotry.
