They hide behind terminology, all the while making a mockery of academic ethics and a correct method of gathering and interpreting data. Like you said, no actual explanation of what "defending China" constitutes as, or why this is bad, or how there is misinformation involved.
You can probably find papers published by their own professors in five min of searching that actually analyze those questions, but these idiots just take it as an article of faith that "thing=bad" and that that is enough.
These types are profoundly incurious about the world. It is all about repackaging what they have been told. Again, articles of faith.
