I understand what you are saying. But the saying about "you may be paranoid, but they REALLY are out to get you" may apply here. Islam is a religion that inspires pathological behavior.
In the hands of extremists you are indeed correct. And there are a lot of cuckoos over there. But we have them here as well. Remember David Koresh and Jim Jones? How about the Arian Nations and "skinheads". You don't get more pathological or extremist than that. They consider(d) themselves "Christians" but their actions are(were) hardly what I think Christ wanted from us. There are good and bad in every single religion. And it is grossly unfair and ignorant to paint an entire race of people or religon with a broad brush based on the actions of some. I steadfastly refuse to fall into the "paranoia" trap because I have lived among good and bad over there, and good and bad over here.
