For the record, I posted this specifically because I feel that it provides a clearer picture of what censorship in China really is like, as opposed to the cartoonishly evil portrayal that most of Western media paints it in.
Although I don't condone censorship overall, I do find it interesting and identify that governments will always find it necessary to impose some form of societal control.
From this study, it seems to me that the Chinese government chooses to prevent events that may cause conflict and violence. That is almost noble, were it not for the fact that it also helps the government maintain a firm grip of control in all situations. I think there is also something to be said for the Great Firewall and how it manages to keep gigantic companies like Facebook and Google from interfering with foreign countries and how it spurs local companies to come up with similar solutions. The drawbacks are all obvious and I don't think it's necessary to repeat those here.
The way that political dissent is managed in the West is so much more chaotic, and generally more violent. The public is split in two (usually) and played against eachother which often results in violence on the streets. Although being able to protest is at least symbolically a good thing, I often wonder if it isn't mostly just another tool used to create the illusion of freedom. If the public is constantly bombarded with misinformation and fear-mongering tactics it's highly unlikely that any sort of unified protest could convert to real, regime threatening change.
So I agree with you that we should be critical of the West, and honestly this post wasn't a jab at Chinese politics in favour of the West, it was more of a learning experience for myself.
