Recently I had a Balkan trip. So more or less I got a bit first-hand experience of such shits. Bosniak muslims and Serbs and Croats are basically of the same materials genetically except for that they diverged at religion hundreds of years ago. They were at each other's throat amid chaos of former Yugoslavia, then the bloody siege of Sarajevo that all of you are well aware of.
Wandering in Sarajevo you'd see many Arabian and Turkish tourists (females always fully wrapped up in black) as well as in Ilidza the suburban resort. Serbs living in the under developed eastern district.
Many have viciously blasted China's "internment" camps and tight security surveillance in XJ (out of religious sentiments?). But to be frank there's no other way around to get rid of their jihadist mentality and teach those diehard bigots useful work skills to make a living other than 5 prayers a day.
Otherwise it would have been the other half of XJ population (kafirs) who'd have sleepless nights vs Uyghurs at high birth rates aspiring to an emirate of their own like neighboring xxx STAN's. Fortunately Chinese are no sitting ducks and trying to nip it in the bud.
