I don't exactly agree with all your talking points but I have to admit that sometimes it indeed feels like I am reading russiadefenceforum not sinodefence. Plenty of those Russia shills also talk shit about China or Asians in general behind the back like that pmc guy. Funny how that behavior is not reciprocal on Russian sites - go to topwar.ru, switch to EN (it will just Google Translate everything, the originals are all in Russian obviously), find some articles on China, and see that the perception is very mixed - some do indeed praise China but many talk shit how China stole everything from them and that every single Chinese tech is inferior to white tech (yes, they do use that term), upvoted comments about "Russia should help Taiwan", yellow peril, bizarre takes like "our Harbin" and all that crap. Russian-speaking part of the internet reads like Stormfront sometimes, seriously, there is A LOT of unabashed overt racism that is not limited to slurs but fully-fledged Nazi-esque racial theories (with whites on top, obviously), and such sentiments are more obvious with the younger generations, something to consider. Compare that to Sinodefence where there are swathes of people who are shilling for Russia more than they support China, lol.
No one is saying that China should ally with the West, what I am saying is that China needs to act on its own interests first. People suggesting to dick ride on Putin's conquest of Ukraine clearly do not care about Chinese foreign policy priorities, they are just enamored with Putin's strongman vibes. China for now will support Russia economically behind the stage through buying their energy exports and will act neutral \ slightly pro-Russia on the international stage.
If anyone dares to accuse me of being pro-West or anti-China, then I suggest them to read my posting history.
