There is even a Satanic Bible. They hold up Satan as a model figurehead.

Aaaaaaand you're moving the goalposts again, asking for a SCOTUS case involving demon worship specifically. I already told you, as did the first two sources, there isn't one, they don't take bullshit cases.

Then why did you claim that SCOTUS said that demon worhsip is not protected by the first amendment? You are the one who brought SCOTUS into the discussion, not me.
