Censorship for obvious reasons, mainly the fact that it takes away freedom of expression, is bad in my books. although it depends on what kind of censorship, censoring inappropriate content such are curse words, provocative pictures and other content that would be M rated where appropriate is fine in my books. on the other hand censoring people opinions, however extreme they are, is just plain wrong; but then they're are exceptions to that too, for example if someone posted something with the intention to offend others then it should be deleted even though its an opinion.
