Briann: "...Arent most Tibetins Budhist?..."
Yes.
They practice(d) a unique form of tantric Buddism.
Highest recommendation for serious reading:
Seven Years in Tibet by Alexandra David-Neel.
The ancient traditions of Tibet teach that it once was a beautiful tropical paradise, prior to the Great Cataclysm when the Earth's poles reversed and a new world was created!
As to boycotting China due to its conquest and genocide of Tibet, this poses a most difficult situation for nationalist Jews.
China has from time immemorial considered Tibet a Chinese province under its domination and protection.
Yet, most disagree with the Chinese Communist government and their barbarous system.
And the Tibetans have had a truly unique culture unlike anywhere in the world.
Now: The Jewish People have since the dawn of history considered Judaea, Samaria, Gaza, and Golan to be Jewish Land, yet our enemies (Arabs) contest the ownership.
China demands sovereignty over Tibet and Taiwan, yet refuses to recognize Jewish sovereignty over our traditional Homeland, siding instead with the Arabs.
Confusing?
Should Jews recognize Tibet as Chinese, in exchange for Chinese recognition of Jewish sovereignty over all the Land of Israel?
