You bet they are, They are American right? Most Americans dont know a thing about things outside their tiny little bubble in suburbia - Amercan christians are just as sheltered, and the knowledge they do have about Islam, or even christianity is knowledge they hear from pastors, or Glen Beck or Rush Limbaugh - a recent study I read showed that die hard Fox News watchers and right wing talk radio listeners are the least accurately informed constituency - and in my experience, a very vocal constituency. I do want to exclude people like PR and many other christians I have met who are the exception to this.
