NONO! the HKese and MACAUese are also HAN nation, thus their special local government flag only announces the difference of political structure compared to mainland.
But if in Tibet the 雪山獅子旗 is permitted, every day the flag is remebering the Tibetans that they are different nation.
There is actually no problem for 髒毒大會, they donot have much influence on the Tibetan in Tibet. After the death of DALAI, every thing will be changed! The Dalai pointed by the Beijing government will be recoganized by the Tibetan in Tibet. Even not, the new Dalai (pointed by this old Dalai) is only a child. It takes at least more than 20 years before he gains the respect. I think the most of Tibetan will not remeber him.
I think our government does not need to change the Tibet politic. The major task at the moment the is the economic development. If the Tibetan all have a good life, who cares about the Free Tibet.
