Yes, you can access slashdot from China. In fact, I'm sitting at a computer in one of Shanghai's suburban neighborhoods.
You're jumping to some pretty big conclusions there. A lot of the Western media covering Chinese affairs do nothing but criticize. I'm not saying they shouldn't criticize, but it really leaves Westerners with the impression that the Chinese government is so cruel and harsh that all the citizens are living in fear. Um, no. We really aren't that affected at all, and I can say (because yes, I have lived in the US and Australia) that life here is no different, except for the annoying fact that I can't access Freewebs.
