Then you should also have no problem if Tibetan rebels "overthrow" China, either peaceably or violently.
China is currently the area encompassed by the PRC. Is it something else? It used to be the area encompassed by the Qing. Before that it was the area encompassed by the Ming, etc. etc. Is this concept too "Western" for you? LOLOLOLOL
As I have said multiple times before, I have no problem of Borjigin rebels overthrowed Song so long as Kublai declared himself Emperor of China. That principle applies to anyone who has the ambition in uniting the whole land in ONE, Tibetan included.
But, if that Tibetan or Han (the Zheng family in Taiwan in 1600s) try to break away from the ONE, I do have problem with them, again regarless their ethnic background. I will support and have served the relevant dynasties in crashing them regardless the family name of the emperor, Borjijin or Asingiro, or Zhu.
I hope this is clear to you by now.
I will not use "China" as you choose to mess things up. In my way, I say this, the area of present day 中华人民共和国 was part of Qing, Ming empires etc. etc.
