Schwartz seems suspect to me. He admits he formerly was a leftist who became a Muslim in Bosnia. I guess he is some kind of neocon chameleon. What will he morph into next?
"we are talking death and destruction" It would seem to me that the reason muslims immigrate to western countries is to escape from these radical fundamentalists, who they say are giving the muslim religion, "a bloody stain." Everyone has a right to practice the religion of their choice, but it is also their duty to be a loyal citizen to the host country in which the reside. If this means reporting a radical cleric who is preaching violence against the population to the police, then so be it. The only way to get respect is to be respectful.
