Again, not true.
In Xinjiang, Han and Uyghur Chinese are 42% and 44% respectively, making the demographics actually similar to the Israeli-Palestinian demography. The Han majority in the rest of China matters not except as a basis for economic development, as the policies implemented in Xinjiang are unique to the autonomous region.
Look, there is no risk of Uyghurs ever taking over the government of China. It doesn't matter if they're 99% of the population in Xinjiang - they're 1% the population of the PRC. That is not the case in a one-state solution for Israel.
I don't know why you brought up the Qing dynasty, as it has nothing to do with the Israel-Palestine conflict. Your understanding of the rise and fall of the Qing dynasty also appears to be fundamentally flawed. Han restoration sentiment was never a major factor during the Qing dynasty, otherwise Wu Sangui would have received a lot more support than he did. Feudal China did not have nationalism, and Han superiority was only a sentiment among the scholarly elite. The common folk couldn't care less who ruled them.
The average person is not a nationalist in any country. They're always mobilized by local and regional elites. If those elites think they can win against the ruling minority by playing the majority culture card, then it's a political threat. You don't face that problem with a cultural minority that's 1% of the population because they just lack the mass appeal.
You might not think this mattered historically, but it very much did. It's why every conqueror of China ended up having to adopt the Chinese language, culture, and elite identity. Otherwise the country's local and regional elites would regard them as "barbarians," who in Chinese political ideology had no legitimacy to rule China. The Manchus were very much aware of this, hence their repeated attempts at presenting themselves as patrons of Confucianism, dynastic continuity, etc.
It's the same with Palestinians and Muslims at large. In their political ideology, Jews have no right to rule over Muslims. Only Islamic leaders have that right. So if Israel wanted to rule over a Palestinian majority, then they'd need to convert or at the minimum, become patrons of Islam.
Which is of course, impossible.
