Maybe. Unfortunately US law doesn't have a concept of "freedom to not worship", so it's tricky for atheists to push back against religious overreach because it's hard to prove the exclusive religious favoritism for Christians in this country as an atheist since atheists are by definition impossible to prevent from worshiping.
It's a lot easier to just say hail Satan and then crush the snowflakes in court since now you are religious, just for a bullshit religion which they can't legally call bullshit on. Because that's the other thing. There is absolutely no legal test of faith. The court must take satanists specifically at their word and push no further. Christianity is a major established religion in the US which means Satan is widely recognized, so it isn't a random cult they can spin shutting down, and it is a religion so they can't pretend the satanist isn't covered by the first amendment protection.
Basically US law is stupid and that makes claiming to be a satanist extremely legally expedient
Genuine question because you absolutelyalready took the time out of your day to clarify the intent with your parenthetical at the end there: is this an ego thing? Like what is it about tone indicators like "/s" that you hate so deeply that you feel the need to go out of your way to create a bespoke, alternate tone indicator which was 10x longer and 100x whiny-er? Where did these feelings come from? Clearly you understand that they're needed, so why do you persist in this nonsense?
