As eagerly as we await the Olympics and the summer games opening ceremony, it seems others have ulterior motives. While the Olympics were conceived as a way to foster competition on a purely athletic level, others see it as a way to advance a cause.
I make no judgement as to whether their cause is just, I just think the spirit of the Olympics is best left untouched by political ideology. Let the performances, and there will undoubtedly be some great ones, speak for themselves.
Tibetans may or may not be being treated unjustly, but find another way to protest. You do your cause no good by interrupting the Olympics.
