"I believe, however, that the hatred of the Chinese Communists, hatred which dates back to Mao Zedong, is much more violent towards Tibetan Buddhism than it is against the Islamic separatists of Xinjiang. Moreover, recently, a senior Chinese official commented that Tibetan separatism is more dangerous than that of Xinjiang. Strange, when we are a religion that preaches absolute non-violence. Besides, I will give you an example of this hateful partiality against my people: in Chinese prisons, the prison guards respect Muslim customs by not serving pork, but they force Buddhist monks to kill cows and pigs, knowing that our religion forbids it."
