This is an important distinction and the basis for the Rule of Law. It is the reason why attacking Islam has no legal basis while Sharia is wide open to such controls by civil authorities. The failure to make this distinction is why the West is in such a muddle over Islam.
I think it is legitimate to question whether a religion that operates (acts, not thinks) like a criminal enterprise can claim a religious status and special protections provided by the Constitution for religions. The Constitution is not a suicide pact. I doubt the framers would have a problem with denying Islam religious protections since Islam would deny to others the religious and legal protections it would claim for itself.
