I am far more fearful of other extremists who live right here in this country - the Christian far-right who want their religion legislated. I am scared to death they want to take away my future grandaughter's right to chose, make her pray in school, teach her "creationism" as a scientific fact and ban her from marriage if she is a lesbian. These are the people I fear and see as the downfall of America - the Michelle Bachmanns, Ann Coulters and the ever-wacky Glenn Beck.
Sure, there are radical Muslims, but the change you see happening in the Middle East is the beginning of a new world there. Women are seeing that they, too, can be equal and pursue their fulfillment. The young people are getting "westernized" and want a new system of government that includes the people. Radicals of any religion will always be there and Christians have certainly been a large part of that in the past. Before we get too holier than thou, remember how many people have been killed in the name of Christianity.
It's videos like this that keep the radicals supplied with recruits and the fear and hatred it breeds fortifies their resolve against us.
