That last part with the qq zone was especially disturbing. But considering the general attitudes of many youngsters in China you're talking about a demographics who are told to follow the leader, not question anything, and not speak up on blatant injustices which happen in their society. What happens is you have people who want to start trouble just to make a name for themselves. It's how it is over there. I have said before that if you show yourself as being too nice and harmless to a Chinese person you run the high risk of being attacked. Whereas if you put on a more cold, even irritable demeanor you will not be put in awkward situations where you find yourself being put under the microscope for perceived faults by a bunch of random local Chinese for no better reason than Shits N' Giggles.
