Yea, Muslims hate other Muslims almost as much as non-Muslims.

More like Chinese money too tasty. Who cares about sand Chinese

It's 100% this.

Best example: I was in Afghanistan when a US Marine walked off a combat outpost and genuinely gunned down a village. People were quite surprised by the Afghani response.

Earlier in the year (or in the previous year), a Quran was found burned in a firepit by Muslim garbage crews on a US military base because the idiot chaplain thought you could just throw away Qurans without people getting fucking SLAUGHTERED. The Taliban whipped people into a fucking frenzy, and the Islamists across the world did the same. In the end, the Taliban used riotous mobs to launch a major offensive against Kabul. 200 people were killed in the overall campaign.

Everybody thought this was going to be way fucking worse. There was no question. There was no debate. This was no accident. The dude went rouge. The base initially responded to the killings as if it were a Taliban attack and tried to send QRF forces to help them, only to realize that the villagers were describing a man in US uniform, not wearing a kevlar, and firing an M4.

Ruh-ro

Dude, just... walked back to his tent. He was immediately arrested and yeeted from the country. Military personally started handing out compensation like fucking candy. "Oh... he shot you're 4 kids and 2 wives... uh... how about $40,000 per person. Your yearly wage is what? $1,000? That should cover it, right? Here's $240,000 and a soccer ball. Inshah Allah."

Even with that, everyone was expecting major, nation-wide riots that were probably gonna kill thousands. But then... nothing happened. Literally nothing. Intel was fucking confused as shit, so they went with patrols in the other areas to see why.

First, this village was literally right next to the combat outpost. This was done because the village was friendly. They had no links to separate warlords or the Taliban. They were just a quiet village that didn't want any trouble. There was no one to rile them up, or seek vengeance with the Taliban. All the other communities had a similar situation. And, they didn't know those specific people. All the nearby villages responded in the same way. "It's terrible what happened. But it happened to them. Not us. Why would we riot?" The distinctions between other ethnic groups was even bigger: "They're not even of our people. Sure, that's a bad thing, and the US military shouldn't do that. But those people have absolutely nothing to do with us. Why would we riot?" Afghanis are just too parochial to care if they haven't been whipped into a frenzy from Islamism.

This is also the same reason why you're not seeing Muslim countries respond to the Uyghurs the way they did to Afghanistan. The Arab ruling class actually realized that the Soviet invasion was an awesome way to get all the Islamists out of the country. Bin Laden originally demanded that the Saudis fund him to go fight in Afghanistan, but they decided they weren't going to pay for him to go piss off Russia. However, they could distance themselves from him, but also use the religious leaders to say that a noble jihad was in order in Afghanistan, and every Islamist really did flood into the country.

After that, the Saudis banned all of them from returning, and stated they'd be arrested on terrorism charges if they ever came back. oops.

Until the Arab world decides it needs a jihad for some reason, the Muslims aren't going to try and liberate the Uyghurs.
