Just to let you guys know, I grew up in China. They call the dali lama an treasonous agitator but no one seriously tries to blame him or believes the blame, he is not really a person of significance in China (only in the western media in relation to China) and he has been gone from Tibet too long visiting celebrities for Tibetans to really relate to.(and most Chinese ppl don't care either way about Tibetans).
Cultural genocide is total bullshit, cultures change and adapt; they cannot die short of genocide. Forcing people to take to retain a certain culture is oppressive and destructive, most companies would rather hire mandarin Hans who can speak to 99% of China compared to Tibetans- so it would only make sense for Tibetans who want better lives for their families to start learning Mandarin and in a generation or two their kids wouldn't see a reason to learn Tibetan except to swear. Most Tibetans would like big cars and houses and most Tibetans would like TVs, ipods, and PCs, but you can't adopt an culture's material aspect without adopting its norms and values to a certain extent. Nomads (and lazy north American natives) cannot exist in a modern world as they were (or whatever remains of their culture) and most of them don't want to. Its just the progressives who insist that people are equal and the egalitarians who in the search of an ideal society and failing to find one in the present resort to destroyed cultures from the past.
