Why is China scared of Tibet?

Oct 2013
Only nationalist Tibetans want independence. Even Dalai Lama is willing to accept autonomy.

Most of us are just want to live a good life which is possible because of vast sums of money that Beijing provides to TAR and Autonomous Tibetan Prefectures in Sichuan, Qinghai, Gansu and Yunnan province. Without this money Tibet becomes siberia without the oil. Nationalists will have to open their eyes and see reality.
You're Tibetan. But am curious as to whether you identify as a Zhongguoren?
