For the same reason that you would not allow something to exist in the same space as yourself, whose defined purpose is to corrupt, diminish, or destroy you as a person, a govt or society in general will behave with identical extreme prejudice. Calling something a name similar to other names does not make more suitable for that classification. For instance, there are many colors of the rainbow, and even black and white; however, there is no color called “anti-white”, for good reason. Likewise, there are many humans with many religions, but “anti-human” is neither a human or a religious classification.
Your attempt to slot Satanism as a form of religion, when it is also a grave social threat, creates a rather unique circumstance, which you seem to try to avoid acknowledging. While it is true, that Satanism attempts to present itself with the appearance of a religion by including the traits of other religions - like ceremonies, practices, routines, formalities, customs, etc, the fact that it IS WHAT IT IS, outweighs its otherwise innocent classification as a “religion”, and the societal rights afforded it.
Satanism pretends to be a religion in the same way that a wolf might cover itself with a sheep skin. The wolf does not belong with the sheep simply because it suddenly looks and acts like a sheep. Only a superficial person would agree that the wolf can now suddenly be classified as a sheep merely because it suddenly appears to fit in with the other sheep. What is underneath the sheep skin is what gives it the credence of being a sheep. Same with any cult, religion, or entity, esp. if it is indiscriminately anti-human or anti-Creation.
When a cult claims that everything living should be dead, and the death of it should be painful, then it is purely anti-Life and anti-Creation. It is not only intolerant of every other religion, it is intolerant of Creation itself. No matter how much you argue that Satanism should be accepted into society as a religion, I am here to tell you in no uncertain terms that ALL society will reject that superficial nonsense simply because it represent a threat to that society.
A threat to society overrides a Constitutional right, whether you like it our not. A threat to society (like the cult which you now defend as being classified as a merely religion, and protected by the Constitution) is a direct violation to LIFE, LIBERTY, and the PURSUIT OF HAPPINESS – and thus, a direct violation to the Constitution. You do not get to have your cake and eat it too. A thing cannot be abhorrent to the Constitution and be protected by it at the same time. Again, for example: “anti-white” is not a color”, just as “unconstitutional” is NULL AND VOID.
This cult (which you wish to call a religion) represents a clear and present danger to Humanity because of its anti-human nature. Its characteristics of being a substantial threat to individual liberties, override any deserved protections afforded by the Constitution. Your argument for Constitutional protections for an anti-Constitutional body is simply unfounded – even silly on its face. You may call Satanism a religion if you wish, but it will not qualify as being protected by the Constitution, the way the Constitution is currently written. Neither will any society on the planet accept it as a legitimate and protected institution, simply because it “pretends” to be a religion, when it is merely vile anti-human filth underneath. It is basically a fact of both, the Constitution and of Creation itself.
In the end, it is OK (and quite Constitutional) to expel a “Church of Satan” cult from a society, as with any other common anti-human terrorist organization. IT IS PROPER AND EXPECTED OF OUR CIVILIZED AND PRODUCTIVE SOCIETY – to preserve the fundamental values of our Founding Fathers…those of Life~Liberty~and Happiness. Praise be to Creator,.Amen.
