The organization also argued that students at the school “have the First Amendment right to be free from religious indoctrination in their public schools” and that “Elementary students are too young to truly run a club entirely on their own initiative” without input from adult members of school staff.
Too young to run a club on their own but old enough to change their gender with input from adult members of school staff.
The establishment clause of the 1st amendment does not prohibit Christian clubs in school. For some reason, libs miss “the free exercise thereof” part. They do however seem to locate the non-existent right to abortion.
