China Revokes Human Rights Activist's Visa

I just read an article that frankly pissed me off. Chine has revoked the visa of Joey Cheek - an Olympic gold medalist and human rights activists. Apparently, though China doesn't need an official reason to revoke any visa, Joey has been speaking out against human rights violations in Darfur that China was involved in - and that was too much for the Chinese government.

Maybe instead of sitting on their high horse, the Chinese government should take a look at their country, at their actions, and see what they are doing to their own people - as well as other people. They are polluting their own drinking water - do they need an epidemic like the London cholera situation to set them straight? They have incredibly polluted air - do they need people to die from pollution or asphyxiation to change this? They inflict human rights violations - do they need the whole world to shut them out to realize how wrong this is?

I'm not too thrilled at having the Olympics in China anyway, but I think they've taken it too far with Joey Cheek. What's your take on this?
