I don't think there should be any religious clubs in a public school. That is what private schools and churches are for.
The School Act is clear that students should be protected from religious proselytizing, whatever the religion.
When I took over a school library the first part I weeded was the religion section.
I removed the Bible stories (in one school it was several dozen) and replaced them with a large selection of books explaining the various religions in the world. I wanted all students to feel valued and welcomed in my library.
Not having a range of books in a school library supporting gays is a message to the gay students that they are not valued.
