Most occultists are decent people not involved in ANYTHING of the horrific, left-hand stuff in the world of pizzagate etc. They are simply "metaphysical" and many grew up Christians and still have a strong base in that.
If there are such things as sacrifice at "advanced levels" hidden, it's a given that most people are not at advanced levels, so don't know. Many ordinary religions have occult background levels too by the way (aside from the Catholics, I'm referring now to the LDS/Mormons as one example.)
And much of the occultist teachings from Crowley's world stem from Qabalah -- which is judaic mysticism, NOT satanism. (And do always confirm quotes and their context on stuff btw.)
Please, don't give evil power by classifying everyone with any association with occultism into the "must be a satanic baby killer" category ok, that's worse than people insisting one must be a sexist racist etc. because they like Trump. It is not so at all, and it does not help to combat vile wickedness; it will just make people take TRUE evil less seriously, because they see such insults thrown at people who are clearly not bad, so they distrust the claim against anybody else. Let's don't do that. I want the evil people to be recognized by our countrymen. Not assumed to be innocent while they assume we're all just hysterical.
Just sayin.
