It's a huge fallacy to try to use "their logic" against them, because none of it is founded with logic. They will say "yes religion in school but not those ones". The same way hypocritical Republicans get abortions and claim "I'm not the same as those whores who are making crack babies", or get vaccinated while being anti-vax because they love sealioning
It’s not by law. A religion is a religion, and religious rights are constitutionally protected. The Satanist Temple has been fighting for abortion rights for years, and even opened an abortion clinic. If Christians are granted representation, then Satanists have the same rights. It’s all or nothing.
That's the point. At the very least it exposes their hypocrisy. At it's best it acts as a shield because when the court says they have to let the satanists do it too they just stop forcing regulation into whatever.
The Satanic Temple has had a lot of success using their logic against them. Their actions have triggered a lot of these laws to be either repealed or nullified by the courts.
Of course, with the courts being stacked by rightists now and making blatantly political, precedent-defying rulings on the regular, who knows if they'll be able to keep it up.
Seriously though, I used to think they were doing good work. Now I am more or less assuming that, in states where they actually need to do this sort of thing, the courts will just shrug and say "Ehhh...nah. Christian chaplains 👍, others 👎. K, bye."
