On Professor Yang Sued "Counter-Revolutionary"

One university professor in East China University of Polictical Science and Law was sued by two of his students as "counter-revolutionary". It so happened that Professor Yang Shiqun criticised on some of China's current policies during a lecture on ancient Chinese language. Two students were apparently offended. They complained to Professor Yang after class and then went to the police and charged Professor Yang of "counter-revoluntionary" speech.  

The matter was posted on Professor Yang's own blog, which has since been removed. But a reprocuded post could be found here. According to the post, the two girls were actually in tears when they complained to him. Apparently they were really into the belief that any statement against the government was unpatriotic. It then raises the question - does one need to totally agree with the government on everything to be patriotic? If so, where is the freedom of speech? 

What's worse is that this happened on the campus of a prominent university on politics and law. One has reason to believe not all of these youngsters are like these two girls but it is nevertheless alarming that the ideology behind this thinking is worrying. Indeed, as many have observed, China's younger generation are increasingly loosing touch on the country's own history. What these two girls have done would have striken an especially stronger cord in those who have exprienced the turmoil in the 1960s and 1970s. For forty years ago, the girls would have had an upper hand in suing their professor. I'm sure no one would ever wish to repeat that all over again. But could we take it for granted that it never will? Particulary given the current state of mind of the young in China? And given their awareness (or lack of it) of our past?
