Nope. If you use force or fraud to deprive another citizen of their rights to life, liberty, or property that constitutes harm. Such activity is properly prosecuted.
The simple existance of, say, the Eternal Church Of The Worship Of Naked Molerat does no harm to anyone. It is only when some individuals do harm that it becomes a problem, but even then that is solved by their imprisonment.
Besides, attacking every other religion save your own merely creates the impression that yours is threatened by them.
Who's advocating such policy?
But how about addressing attempts to defraud America and it's citizens by referring to any self-declaration of a "religion" as a front to plot and plan against said citizens?
And again -- WHO shall be the arbiter of what constitutes such a thing as "harm"? Especially when such arbiters are increasingly commanded to abide in "moral relativity" because it is more "tolerant"?
Let me simply ask you to imagine a purely theoretical scenario:
Would you believe the United States of America -- should Satanists and Muslims become dominant in numbers -- would still retain the same ideological course in "liberty" and "freedom for all" as we have since our Founding Fathers?
