Clambake you wrote: I use to have an interest in the Occult and from my research this so called Satanism it was just an extreme form of atheism which seemed more interested in pissing people off than being an actual religion.
Oh its an actual religion all right.
A lot of the so called rituals were actually just developed as a mockery of Christianity. Goats instead of sheep, Drinking blood as oppose to kosor diet, inverted cross, etc etc.
Clambake that is Devil worship or in other words Inverse Christianity, not Satanism.
Historically the well known religions that demanded blood sacrifices were the Abrahamic religions. Today those blood sacrifices are mostly performed by 16 year old kids who think they are doing the will of the Devil by killing a cat. Their background is Christianity, which they think is true and that's why they do idiotic things as an act of rebellion. They get their ideas from the OT.
