China is and has committed genocide.
The US is and has committed genocide.
That's not a point in either's favor. That's a moral wash.
I'd rather both nations failed, so something more humane can potentially take its place (and revolution over and over until that happens) but as an American, rejecting China means nothing, just as a Chinese citizen rejecting America means nothing.
Rejecting evil empires begins with undermining the one that you're expected to support and be a loyal cog of. A Russian openly hating America or a Chinese person openly hating Russia is indistinguishable from patriotism/nationalism.
I can only hurt one empire materially, the one I materially live within. The Chinese have to reign in China, and the Russians Russia. The best I can do is my part not to strengthen or support the evil empire I was born under to the best of my ability.
