Let us construct a hypothetical situation where our geopolitical adversaries (Russia, China, parts of South America) had spent the better part of the 20th century backing equally hypothetical Jihadist (or even Reconquista) separatists in Texas.
Perhaps the situation in Texas deteriorates when separatist Texans return from jihad in Syria, and some more violent fringes, armed and trained by Russia and China through proxies, begin widely-publicized attacks on civilians in California.
Perhaps the most ethical response by the US would be to deploy prisons and security services to Texas, and use technology to monitor potential separatist action within the state. Certainly there would be human rights abuses.
Now who is at fault, truly? The US? The separatists? No, of course not. One could place moral blame at the feet of our geopolitical enemies for encouraging this in the first place, but this is simply the reality of political action.
Just to be clear, what is happening to the Uighur people is horrific and inhumane and absolutely disgusting, but I will not allow this humanist sentiment to be perverted by propagandists to manipulate otherwise intelligent, compassionade liberals into nationalists and xenophobes in the name of maintaining the Western hegemon.
The anti-Chinese sentiment that has invaded the internet over the past several months has gone well beyond 'legitimate criticism of the Chinese government', and now sounds more like a racist, imperialist drumbeat for war. We should all be suspicious when fascists and libertarian capitalists find common ground and call it humanitarian.
