There are people going to work every day in China doing the job of censor and they reckon they are doing something good and patriotic. Even at the level of policy makers, the censorship is there in the first place and continues to be there because many legitimately think it is good for the country.
Without being educated on a topic, you're unlikely to figure out most things about it on your own. Without an education in rights and civil liberties, you're unlikely to conclude on your own that censorship in principle is bad.
If you want to make a difference, get off your high horse and construct an argument against censorship for someone who wasn't educated in a Western country like you were.
