Are you trying to define Islam as a religion or are you trying to justify the actions of muzzie terrorists because they're based on their religion?
Islam is based on a false worldview, but it's still a religion, at least as most people define the word.
What's hard for many Americans to believe, or at least to say, is that all religions are not equal. American culture, to the extent it exists, is more compatible with the Jewish and Christian faiths than it is with any others.
Because we don't all share the same faith, though, this subject is one that most Americans feel profoundly uncomfortable discussing.
