That "muh uighurinos" meme is so tiresome. I have 0% knowledge on the subject, but judging just by what the same Western propaganda says about Russia, I'm 100% sure that the this "annuda shoah" is 15% twisted and overblown truth, 25% lies that put the sins of the one who invented them onto his adversaries' shoulders (i.e. blaming others for your own misdeeds - this can range from the psychological defense of "hey they have the same shit as we do, but even worse!" to intentional false flag operations), and 60% pure unadulterated fiction that doesn't have anything to do to what really happened.
