The head of HR at my office has a Church of Satan coffee mug on his desk. There's nothing else in his office that is weird, and no other indication that he's a Satanist besides this mug. I suspect you're envisioning a fat, unwashed man-child with a ponytail, but this guy is just a regular-looking middle-aged man dressed in a business casual sweater and jeans.
The CoS is based. Only religion I am aware of that explicitly says that pedos are bad. Juuuuust saying.
There's a fucking hilarious scene in Silicon Valley where some high up at Yahoo is initiated into the Church of Satan in a "dark ceremony". Trying to find the clip but it's impossible for some reason
Unironically probably better than a blue hair overweight woman HR boss.
