There is no irony here, you're not understanding the context. It's never been against the law for a teacher to show them here in school. But now they're forced to, even if they personally disagree with displaying and perpetuating religion in their public school classrooms, when separation of Church and State is such a core component of our Constitution. A huge amount of our state was against this violation of free speech, but our governor signed it into law anyway.

The library is still a resource for those who wish to learn more about religion, and I certainly used it while learning about various religions that I was not allowed to research at home.
