So that's not what the actual text of the bill says.
Go read it. Nowhere in that document is there any prohibition of any religion.
I'm not saying that this won't absolutely be abused to express favoritism towards certain religions over others. Of course it will. But that isn't in the actual text of the bill.
Go read the OP, that is not what the OP says.
From the linked article.
Here’s what happened: As they have done with other cases involving religion and public schools, the Satanic Temple said it would gladly send chaplains into Florida’s public schools as soon as the new law took effect. These Satanists are not actual Satan-worshippers, even though
they have legal status as a church, but rather a secularist group, hoping,
in their words, “to provide a safe and inclusive alternative to the religious clubs that use threats of eternal damnation to convert school children to their belief system.”
DeSantis took the bait.
He announced that no Satanists would ever participate in the chaplain program. Why not? Because Satanism, DeSantis intoned, “is not a religion.” And with that statement, DeSantis had the Founding Fathers rolling in their graves. DeSantis’s declaration was exactly the kind of thing they took pains to forbid.
It is DeSantis making the decision as to what can be a religion.
