I just came to a realization: the Uyghur genocide story is a litmus test.
Near the end of the Qin dynasty, the eunnuch Zhao Gao became the power behind the throne. In order to purge those who might not be loyal to him, Zhao Gao one day brought a deer into the court, and told the Emperor that it was a marvelous horse. The Emperor, confused, asked Zhao Gao if he was joking, since this was obviously a deer. Zhao Gao turned to the imperial court and in complete seriousness, asked the officials present to tell the Emperor if this was a deer or a horse.
Some officials, fearing Zhao Gao's power, or wanting to court his favor, told the Emperor it was a horse. Other officials, unwilling to bend their dignity, maintained that it was a horse.
Zhao Gao memorized every official that claimed it was a horse, and later had them killed under various pretexts.
The Uyghur genocide story is the modern version of 指鹿为马. When the day of armed reunification comes, you can be certain that the world will be divided into two camps: those who joined in on the genocide accusations, and those who refused to be a part of it.
Actually, if I were to analyze the whole "Uyghur Genocide" farce with a Chinese mindset but in a Western/US position, I say that this is actually genius smearing tactic. It's genius precisely because it's not true, And it achieved just the desired purpose.
1. It's an allegation that will remain an allegation. So it would be an ongoing topic to annoy China with. It's not a done deal.
2. Since it's NOT true, there are no pressure upon the real Western Judiciary Institution. They DON'T have to prove whether it's real or not with real evidence. This gives them both the benefit of such allegation being misinterpreted by gullible general public as being prove true, and bear no consequences of Chinese counter evidences to disprove it. It's like China already felt the damage from a slander, but at the same time, can't really accuse and prosecute the West/US for slander, because they didn't technically determine any of the allegations to be true.
3. Because it's not true, but at the same time, has some level of internet popularity, it become kinda like a spetre/urban-legend. This kind of thing is very difficult to counter with remedial media action/activity.
4. Even though it is NOT something that is proven, because the level of popularity and recognition among the people in the West, congressional/legislative action can be taken to give the US excuse to target Chinese industries as well as economical geostrategies in Xinjiang.
This is why I think the worst kind of modern war fighting is Media war in this current distributed Internet/Digital Era. It is just so entirely new, and very hard to deal with, especially for large complex countries in the rise like China (potentially India as well, in the future).
