Looking at this situation from the perspective of Pakistan however, I can't imagine any logical Pakistani would want the Uyghurs to be independent. Think long and hard about it. Currently, you have a massive and powerful nation who borders you and has been very friendly. If Xinjiang becomes independent, what you will have will be a failed and weak state like Iraq where the CIA and US military can set up their bases to harass China proper and would either be useless to Pakistan or perhaps even hostile. Considering that Pakistan has a hostile regional rival that has 8 times its population, that would be a dark place to be in to lose China as a neighbor.
The issue is not about Uyghur independence, as that is a distant dream. No neighbor of Xinjiang supports it. Maybe in the future I could see it, but not anytime soon. Of course, Pakistan has cultural, racial, linguistic, and religious affinity with Uyghurs. We share much more in common with Uyghurs than we do with the Chinese.
The allegations are disturbing from a humanitarian and Islamic perspective, as we put much focus on the honor and dignity of Muslim women. Indeed, India was invaded by the Islamic Banu Ummaya empire because one Hindu slapped a Muslim woman in the face.
However, it is good for China that so far all allegations have been from CIA puppets, which most Muslims do not believe anymore after the lies perpetuated to invade Afghanistan and Iraq, and continued lies against Iran, Turkey, and Pakistan.
Xinjiang would be another Afghanistan. A failed state being infiltrated by Wahhabist CIA backed terrorist groups and kept in constant chaos so it can be easily dominated by the US to prevent Eurasian integration and the Belt and Road initiative from succeeding. That's really the main driver behind all of this Uyghur related propaganda, to disrupt Eurasian integration and foster hatred between China and the Muslim world.
I would ask you to stop using Wahhabi as a blanket term, as it is disingenuous. We are talking about a sensitive issue, let us not sully it with Western doctored terminology which has no meaning on the ground.
Afghanistan has been forced into war/proxy war constantly for the last few hundred years. Yet because of this, we see that today, it is the only place absolutely free of Western influence in the Muslim world and the only place where US has failed utterly to gain a foothold.
There are many positive signs coming from Afghanistan, and it will be very important in the future.
