I'm in the UK and the Chinese people I know only need to watch the reporting on the BBC to be convinced that a lot of protesters are anti-China and potentially propped up by foreign forces: Violence, attacks on government buildings, attacks on the Chinese flag, flying foreign flags, calling on the Brits and Americans to intervene, etc.
The actions of these protesters have ensured that the Chinese government cannot do anything but standing firm.
I don't know what Chinese TVs show to the public on the mainland, but if they show what the BBC shows then the people can only be outraged and absolutely against the protesters.
The way these protesters behave has completely drowned any message regarding democracy, which the Chinese public might actually be receptive to, though indeed that would be censored by the media on the mainland. That's another reason not to hand the government the stick to beat them with.
