I don't have much of a problem that he once embraced Communism. Lots of people have been duped by it.
I'm shocked that he would have anything positive to say about Communism and Mao, but on the same page he says the earth is our "Mother" and, (I'm paraphrasing), "she's pretty mad at us", so I'd expect that he would be all for socialist environmentalism.
HOWEVER, THAT REMARK ABOUT US BEING PARTLY TO BLAME FOR COMMUNIST BRUTALITIES AND MURDERS BECAUSE WE WERE HYPER-SUSPICIOUS: I FIND THAT REMARK DISGUSTING AND OFFENSIVE!!!
Consider the circumstances. We betrayed him. His troops were slaughtered because we didn't do what we said we would do. His government in exile is in India because we set it up there. He can't go mouthing off about China, he has his people in India and in Tibet to worry about. The Dalai Lama pushes it as far as he can. Some people are still getting out. Tibetans are guests are in India and Nepal. They start causing trouble with China and they are in a precarious position.
