The issue with the China apologist comments is that their intent is to damage control by attacking the negative sentiments that would make the country look bad and steering the conversation towards the evils of other countries, i.e. whataboutism. This behavior is so prevalent online that you'd be hard pressed to find any discussion that criticizes China without it.
I'd also find it frustrating if in any thread that criticizes the US there would be comments about how China is worse. That might be the case, but it doesn't minimize US' problems and only distracts from discussing them. Yet such comments are much less frequent--I'm not sure if I've ever seen one.
