TIL "Jezebel" is a reference to the bible.

Without the bible, people still have dictionaries if they don't understand words or references. Or they could use Google. I don't see why some books would be "too crucial" not to ban in a law banning books intended to protect kids.

If anything, I find it easier to defend a ban on religious books in (public) schools.

Typically biblical references are references to parables or lessons, not single words that can be easily looked up in a dictionary.
