I understand that we all at HN know about the media censorship, but when you are trying to convince someone who disagrees, some evidence would be very useful.

Depending where you live, there are likely laws prohibiting communication in public about sexuality (think graphically explicit pictures where accessible to children, think non-standard sexual expression), politics (think inciting hate against groups of humans and calls to kill them), culture (think sharing a song you really like with your peers), and many more.

You might say that these restrictions and censorship is okay because you agree with the given reason. But exactly like that, people in china might agree to the reasons their government is giving them for their censorship. Who is right?
