Whenever an ignorant Westerner starts parroting the propaganda line about supposed persecution of Muslims in China show them videos like this - a thriving Hui Muslim community deep in south western China. Remind them that there are more mosques in China than in all of Europe and America put together...and by a large margin too!
I suppose it is a case of projection, since their own countries do it with minorities such as Asians.
On this topic, there is a book called The Karma of Brown Folk by Vijay Prashad which tackles how the myth of the model minority came about and how it is weaponised against minority groups like Black, Indigenous, etc. I haven't read the book yet but how these minority groups came to be in the imperial core is probably a factor. For example, Black Americans being descended from slaves while many Indian have to fulfill strict visa requirements to "prove their worth" to be let into the imperial core.
Pretty much on point.
