As someone who have spent 13 or so years of their life in China, I absolutely agree with this perspective. The culture of modern China seem to support a strangely "macho" image particularly for men: it's acceptable and maybe even encouraged, for men to be overtaken by rage, and thrash and kick around while yelling things. [1] It looks like this mentality is reflected by the politics of china as a whole.
[1]: This is actually very accurate to how people get angry in China, I've seen teachers, businessmen, even customers, rage in this characteristic weirdly macho way. https://youtu.be/aCdFec3uu_g
