Oh shut the fuck up.
Let's do the same argument in this thread too, One Track Mind.
You know why the Chruch of Satan chose to do it on June 6th and make it international and public right? To antagonize the Christians. To glorify the mark of beast. This was done deliberately to use the likeness of Satan as social commentary and transgression of Christian morality. It had fuck all to do with the ritual itself.
You know who really likes Satanic Black Masses, performed like LaVeyans even?
The Satanic Temple. They even hold the record for the largest black mass. They do it partially for the same reason the CoS did it. To antagonize moral fear. Don't let their use of it for political activism make it any less antagonizing to the Christian part of nomos for you.
And since this is a left/right world there really is no chance for any one thing to transgress both of these branches of subnomos.
If you want to antagonize the other branch of subnomos you hold a white pride rally...
