Of course these people have a political agenda. The real Satanists, full on sacrifice with black mass and human sacrifice/desecration type Satanists would probably keep a lower profile and laugh at these people in that they ultimately were futhering their agenda while completely ignorant. If they exist...

It’s an onion. Layers under layers. The core of believers that are completely dedicated to the Adversary is deeply hidden but very real. LeVay’s Satanists are just the topmost layer.
It’s a seemingly-innocuous public face that not only helps mind-numb the gullible public, it also serves as a forum where the real, serious, dedicated, and dangerous opponents of God can observe and recruit potentially useful persons for deeper things.
The most dangerous do not wear black robes or draw pentagrams on the floor. They wear suits and ties and have impeccable public personas.
