To make it more simple for Nimo Kaskmiris, Pakistanis, Indians share the same culture language,history,food and genetics. Chinese don't share these things with Tibetans and Uighurs. Another difference it was outsiders that separated us and it was Chinese that forced their rule on Uighurs and Tibetans.
Witnessing again and again point out many Indians' 'dual standards' applied to Kashmir vs Tibetan/Uigur, suggest u read more China's history (or don't distort it to suit your need)
Facts against your fancies
1) Uigur played a very key role in China's history/Culture. Uigur (回鹘)saved Tang Dynasty from collapse during a big revolt, and Tang Dynasty allowed Uigur Princes to take on Tang Dynasty's Royal surname Li. Later
Uigur princes even ruled North China (incl. reaches of Yellow River) after fall of Tang Dynasty (in China's history that chaotic period is called 'Five Dynasties+ Ten States 五代å国 i.e. China was broken into 10+states)
2) Uigur used to live in Mongolia Plateau, Gansu and Qinghai before migrating to and settled down in Xinjiang and then was converted to Islam durng Song/Yuan Dynasty. Xinjiang was domiciled by different ethnic groups long before advent of Uigur, Huns, Mongolians, Hans and even Uzbek (during Han Dynasty it was recorded of Uzbek there). Many Indians distort or selectively disregard this part of history in order to allege Hans 'intruded' to Xinjiang and took 'indigenous' Uigur's blah blah...
3) During Tang Dynasty, King Srongtsen Gampo of Tibet and the following King married Tang princesses and Central China's culture/religion/technologies since then started to take root in Tibet too. Not until Yuan Dynasty did Tibet become part of China as swept by Mongolians. True as it is , most empires were forged through blood and fire and intrigues. Many dynasties (Yuan, Ming, Qing) played the trick of supporting one faction but oppressing others in Tibet. For example Dalai Lama, or Pancheng Lama were different factions 'played' in China's emperors' games.
4) u mentioned 'genetics' and language. very puzzling as it's clearly not a field u are familiar with at all. Hans/Tibetans are of the same genetic groups and language group while Uigur isn't. But what is your point? Looking back at India, are u saying xxx ethnic groups can't stay within in a nation if there's no same genetics/linguistic heritage?? (again dual standards)
And what about Kashmir?
I don't understand your reading of history. Majority of Kashmiris are Muslims. Unlike their Hindu Raja they preferred to be in an Islamic state at partition. Wasn't (Isn't) it a fact? we recognize status quo i.e. Kashmir is separated by in 2 countries (ind & pak). it's unnecessary to 'revise' history to justify Indian rule there (it's already
an established fact )
Before British Raj, in my opinion, India was fragmentedly composed of different self-ruled states. Ironnically It was Brit. who tied them together before 1947 Independence. Even that Monguel Empire only ruled parts of Today's India... It's no shame to admit this fact similarly China's ancient dynasties were on and off controlling some parts of Today's China territory. Empires rise empires fall... apart ... The difference seems India in history lacked a consistent 'Centralized' regime like China.
Kaskmiris, Pakistanis, Indians share the same culture language,history,food and genetics. So what??? do u agree Vietnam Korea, or Jpan also share all those with China.

u were off topic. then I followed your track.
