No, unlike many here, I am not one for banning books in the public library.
Just leave the magazine there and take the responsibility of being a parent and decide what your child can and cannot read and do not dictate what other people's children cannot read.
So what’s wrong with reading it to the school board then?
I have a feeling that some current First Amendment supporters might change their tune if a librarian started stocking the shelves with The Turner Diaries, White Supremacist magazines, and Christian Identity works.
All libraries practice censorship, in the sense that not every published item can be stocked, and somebody has to decide what to stock and what not to stock. The real question is who gets to make those decisions.
