They pick one side and argue and justify away the crimes “their” Side has done
That's a heavy oversimplification of everything on there... I see the folks on grad being mad about bad decisions by China just the same; they just heavily scrutinize negative news for bias or misinfo, as people should do for everything.
If you do scrutinize your news and sources, I think it's only natural that you'd end up being very anti-west/imperialism, and far less anti-China, specially considering the grip western media and news have on the world. The two are just not equivalent at all.
The People of Tibet might disagree there
Here's an example of that. The fact that China's education system makes sure ~90% of Tibetans can speak their cultural language compared to the ~8% of North Americans that can speak theirs means they're just not equivalent. The only countries accusing China of such a fucked up crime like cultural repression are western ones with a political/economic interest for doing so. Muslim countries and the global south side with China on this and Xinjiang.
