Teaching and promoting a singular belief is 'illegal'. Teaching about beliefs in general is absolutely legal my friend. World Mythology and World Religions are a common class in highschool. For decades.

There are no current laws that force schools to tell a parent if thier child is claiming to be part of a certain religion.

If your claim is true. A law for that and not specifically about pronouns should be pass. Correct?

Wow. The smarts on you. So there are laws in place to force the schools to tell parents if a child identifies as a certain religion in schools?
