I don't agree with OP, and I'm willing to hear why you're correct in that assessment, but can you elaborate?
To be explicit about each other's assumptions, I think Race (however ill-defined or specific construct as it may or may not be), is not the same thing as Country, Political System, Culture, Religion, etc.
Understanding racists these days mostly use euphemisms and codewords, and it's a devil's work sometimes to figure it out, in the "Principle of Charity" sense, I read that post as being a critique of China's political and cultural systems in general, and their sport-league / development in particular, leading to specific societal outcomes. I could be extremely naive though but I'm willing to learn if you may provide more backing/thought for that?
There is a strong theme of "Chinese people are drones" when you hear about whatever the west's current propaganda issue is. I'm not sure if the poster was explicitly trying to hint at that, or just repeating derived ideas from those that really think it.
Lots of posts about how the CPC isn't really doing the will of the people, they are just following and the people are too docile or subdued to resist. Chinese people are bad at team sports where an individual contribution can play a big part. They are only good at the ones where they all do the same thing.
It ties in with the western ideology that we are unique, dynamic, flawed but able to push ahead in a way collectives aren't.
I will also posit the downplaying and discrediting of Chinese tech and industry is also related with this mindset.
