Its certainly not a dud. Those allegations are working. The hate crimes against Asians are rising across the West precisely because of the Anti China propaganda.
Muslims Governments may not support due to national interests but among your everyday Muslims Chinas image has taken a hit. Follow Arab Media, Muslim media and you'll realize how the opinion is being shaped.
Your average layman doesn't possess the critical reasoning to differentiate Real from Fake and just doesn't have the time to go about researching allegations. He simply consumes what's being fed to him.
1. My apologies first, have to go all language police here, the word dud means something that does not work properly.
Unless we believe hate crimes were the stated goal or unstated goal of this policy smearing Xinjiang, then it is a dud.
Since the smears started under Trump, who people claim is a racist, then it is plausible that this policy about smearing Xinjiang is to provoke racial attacks in America. That would be official US policy, to prosecute their own minorities. That I feel is a stretch, but that is America, so who knows.
2. What I read from a couple of racist commentators, that the crimes against Asians lately in the USA, were still mostly committed by the same people, the blacks!
That is what the crime stats say apparently.
The more things change, the more things stay the same.
