The Satanic Temple doesn't worship Satan either really. It's Pastafarianism, except more metal. It's a parody religion designed to push back on Christianity, going through the motions of worshiping Satan entirely to trigger Christians. You'll note in the invocation that she said to "Let us reason our solutions with agnosticism in all things, holding fast only to that which is demonstrably true." The existence of Satan is not demonstrably true and the Satanic Temple doesn't claim that it is. They're metalhead non-theists going through the motions of invoking Satan in order to get Christians to freak out so they can make their points and make the Christians look dumb. And when I say Christians, I mean these Christofascists / Christian Nationalists we're seeing trying to take over government, society and culture. They don't target peaceful Christians going about their own business. They target Christians in government (or other positions of authority) being authoritarian assholes.

There's no such thing as devil's and demons

This is more than likely by the The Satanic Temple or TST. They don't really worship them.

Did you even read the prayer that is quoted in the article? It's pretty great, even from a secular standpoint.
