For those of us in the US we do NOT enjoy the right to free speech (even though it is in the constitution). The supreme court ruled in the Miller case that "obscene" materials are not protected under the
1st amendment and can be banned or
regulated; translation: regulated censorship is constitutional thanks to a few
activist judges who wanted the government to impose its morality on us. Basically if the subject or content is sexual in any way then whether its obscene or not is up for majority vote; they actually said if the average person would be offended by it and think that it had no artistic value (if you weren't offended by it or thought it was a work of art why would you want to
ban it in the first place). This is why it is illegal to give porn to minors, because it shows sex even though this should be decided and enforced by the parents the government is getting involved. Also there's no law against showing violent material to minors, so basically its worse to expose them to consensual sex than murder.
