Libraries, Barnes & Noble, Borders and many other libraries as well as book stores already in essence ban books. Try to get your library to purchase anything that isn't ridiculously liberal. They refuse to purchase any conservative books or videos. Many of the book stores don't put out conservative books or manage to always be out of them, hide them, etc. It's ridiculous how the Democrats, Socialists and Liberals, though I repeat myself, always talk about freedom and do everything they can to limit free speech and discussion of open ideas.
