Incidentally, I was banned for saying that China would end up with less deaths due to the coronavirus than the US, as a result of their stricter interventions, which turned out to be true. The moderators of that subreddits decided that it was such an egregiously incorrect point-of-view that it had to be deleted, and the poster banned.

So no, r/geopolitics isn't really good anymore. It was interesting a few months to years back, though. But now it's mostly biased, moralistic and americentric takes with artificially limited debate, with such scathing and interesting discussion as "Western culture is the best culture, and that's why the US will be an eternal empire", or "China will be sublimated by the US just like the US beat Japan". This is a stark contrast to the more realpolitik, realist discourse of yesteryear. Non-China related threads are better, though.
