The real danger to religious freedom comes down to this- if Scientology (TM) Brand Artificially Religion Flavored Quasi-Self-Help Product is allowed to pervert the concept of what a religion is by being allowed through its chicanery to enjoy a real religion's rights and privileges, then the very concept of freedom of religion is forever cheapened in the mind of the people, and ultimately everyone's freedom of (and from) religion is threatened.
It is not a religion, it has never been a religion, it will never be a religion. It is simply a corrupt business which cleverly incorporated a vague "religion angle" which comes and goes at said corrupt business's convenience to get around taxes and laws pertaining to medical fraud. Period.
