Yes it is censored ship but it goes beyond banned interviews, they filter all information. I think the most effective tool is selective teaching in school. Whole blocks of history are being ignored or re-written. The history teaching emphasise on how China has been bullied by the whole world in order to seed patriotism, while numerous TV shows and movies make sure to keep those memories fresh.
The video shows educated people probably around the Beijing university that is not really representative of what is really going on. 99% of the population is oblivious and brain washed. They have really no idea about the tiananmen massacre.
Sure, this is an extreme case but when living in china you are confronted daily to behaviours that defies our sense of moral. China should pour founds into education but they will never do as educated people would be the end of "elite controlled" china of today.
I have been living in china for over 10 years and I came to the conclusion that what you assume here as being "basic human instincts" is really the result of the culture and the education that shaped us. Let a human being grow with no rules and awareness of good or bad, where the only law is "what is good for you well is good", then you end up with this kind of behaviour.
This theory would have had way more impact without quoting any names or making any direct accusations. It would also have had the benefit to spare his reputation.
