The West does not want any opponents. Of course they don't. The 'communists', 'not a democracy' angles are just for public consumption.
The rules are set by the dominant power. So when they complain about China not playing fair or by the rules what they really mean is that they don't like that a country becomes strong enough to set their own rules according to their own interests
I don't really have a problem with what the US is doing or trying to do. What I can't stand is that people actually think this is good (USA) vs evil (China).
Of course the West wouldn't welcome economic competition from China even if it were a flourishing democracy. Still, let's not lose sight of the fact that there are real moral differences between the US and China.
Note, for example, that you can say whatever you like about the US on this board, and the worst that will happen to you is that some people downvote or flag your comment.
I do not see China murdering people around the globe with drone strikes. And then not punishing everyone involved with death penalty. To me it is very clear which is evil and has evil population which keeps supporting these actions even if they still have some tools to fight against them.
China has the death penalty, and executes vastly more people per year than the US (~800 vs a handful).
You can (and should) protest certain aspects of US foreign and military policy within the US. There is far less latitude for internal criticism within China. Just try bringing up e.g. the Uyghur genocide and see how far you get.
