nationalist chauvinism

That's a new vocabulary for me.
For sure. Blind patriotism is something that I definitely do not get, both in the US and China. It's stupid, alongside blind opposition to socialist policies like basic healthcare and livable wages. I sincerely hope the US improves on that in my lifetime.

American imperialism

I see that in Chinese propaganda too. I may be biased, since I live in the very country the US and China is trying to have an influence in. I could discuss with you about it, the nuances and my perspective of it, but it's way past my bedtime now and I have work tomorrow and other priorities, so I probably won't reply. You are free to message if you want.
