> They also have banned some forms of pornography.
While I get that it's not what you mean, I believe most of the world bans certain type of pornography - namely child pornography? (Although the world doesn't agree on what a "child" is in terms of age).
I'm not sure it's controversial to ban some forms of expressions that are considered to be more or less universally only possible by harming the innocent (see also: bestiality).
Personally I have an issue with possession of data being a crime, as it is such a dicey proposition when it comes to planting evidence etc. But I don't have any problem with it being illegal to eg: manufacture child pornography.
