We can gather information and compare, to see which one is true. Lots of stuff to google.
I'm not saying history by communist is wrong, but since most people are brain-washed to hate communist (like most of us are brain-washed to believe DaLai is, at least, not good), simply show them how westerner themselves look at it. What we need is the result, to show and convince what it was.
I respect him as an old man, 72 years old, I heard. But it's disgusting to look at history, read what he says today, and guess what's really in his mind. He seems so vicious and deceiving to me. One of the LZ is right, we are all selfish, we only want to say what's good for ourselves, till the very end, we cover our guilty deep inside. Anyway, he might be the "prophet" of this world for another 20 years if he is clever and sly enough to "act neutral"..
People here are naive, too naive. Maybe I'm naive, too. (Sounds like I can speak better than DaLai Lama? lol)
