If you want to know how censorship can be good, look at all the crank theories and beliefs that people expressed that the majority of the population would regard it as 'wrong', and said population would be right. But the government couldn't censor their views, because it would be against our constitutional rights. For better or for worse, we think the freedom of expression outweigh the benefit of having a government ban expressions. I am glad that doesn't happen here in the Western world, but it's a good idea to try to think from their point of views of how censorship might be good.
