Counting radical Muslims

There are thousands of Muslims willing to die in the name of Islam. Hundreds of thousands agree with them. Millions support stoning, whipping, and the amputation of hands. The numbers of Muslims that either agree with radical islamists or barbaric practises like honour killings, stoning, and public flogging is staggering.

Is THAT enough to call Islam a threat to us?
