Why Should it Matter What We Read?

Today at the public library, I saw a shelf of recommended reads for Banned Books Week, and it got me thinking. Why in the name of the Angel Raziel would a book be banned in the first damn place? Censorship is just The Man’s way of saying fuck you to curiosity. I once read a rabbi who was so afraid of his kids going OTD that the only reading material in his house had titles like How the Rabbi Went to Israel and Kept all the mitzvos! I get not wanting your kids to leave the fold, but there is such a thing as extremism in any religious community. Thoughts?
