I have a hard time seeing Islam as a religion. I do not want it protected. I would support an Amendment to the Constitution which either promoted Christianity or excluded Islam. I'm all in favor of that.
But, honestly, we look like idiots if we say that the First Amendment is about protecting Christianity.
[T]he real object of the [F]irst amendment was not to countenance, much less to advance Mohammedanism, or Judaism, or infidelity, by prostrating Christianity, but to exclude all rivalry among CHRISTIAN sects and to prevent any national ecclesiastical establishment which would give to an hierarchy the exclusive patronage of the national government.”
