Is it a Religion?

I don't read into this that governments (as opposed to Congress) can't interfere with religion. If that were true, any criminal could simply arrange their affairs as a church. Is Islam a religion or a political belief? And why do we tolerate a religious belief that we would not tolerate if it was a political belief? I think we are a little too sensitive about interfering in peoples religion.
