There is a long dispute among the Tibetans in exile in India concerning the devotees to another religious figure called Dorje Shugden. These people chose to workship Dorje Shugen for some reason while the Dalai Lama ordered religious persecution against them and used various means in his power to cleanse their worshipers from his group of followers including the use of secret police and assassination. The Dalai Lama and his group in India has a unofficial status of regional government where they control the education, monasteries, policing, even employment.
The Nobel prize winner Dalai Lama ordered persecution of the worshipers of Dorje Shugden even when he is in exile. Imagine what he would do if he had control over the entire Tibetan Autonomous Region.
Need proof? Here is an appeal letter written by the followers of Dorje Shugden to the then prime minister of India. It is a scanned image with certified stamps so you know that no one had fabricated it. I don’t even know this matter existed until it surfaced recently again. In fact, the followers of Dorje Shugden will stage a protest against Dalai Lama when the Olympic torch passes India. How ironic!
