I can't even to vote on this. Every option is equally important to my mind.
We boycott, and the west stands to potentially lose economic ground with China. As an Australian at least, I can see the economic importance of China to Australia, and I would imagine it's not much different for the US and Canada.
We don't boycott, our weakness for standing against the Fulong Gong killings and the world in general will possibly view each other as less humanitarian.
The games are about sport and coming together as a world to celebrate sports, so it's of social and cultural significance too.
But as for not helping the people in Tibet, I disagree. How can a whole world of competing nations boycotting the games not have any impact on this?
