What I see is anti-China propaganda where everything bad is denounced when China does it but ignored when it's the west and their allies.

I see many more post about "China evil" than I see about Saoudi Arabia or Israël.

In fact, the "China evil" propaganda is very often a form of whataboutism to avoid the same or worst problems in the west. In French there is a say that goes like "it's easier to see the straw in the eye of you neighbour than to see the beam in your own eye."
