The idea of "Harmony" is strongly connected to collectivist ideology. In the west, mainstream political parties tend to embody particular aspects of collectivism, while parties that completely embrace or reject it are relegated to the fringe (eg. Communist or Libertarian parties). In the US, the right-wing tends to be highly collectivist when it comes to the military/law enforcement (eg. "Support our troops"), religious practice, and national identity (eg. "Patriots") while the left-wing tends to be more collectivist when it comes to government programs and policy (eg. Universal Healthcare).
Wrt my own political-economic convictions, im a socialist far more left than "typical left wing american", which are not socialist (so not actually "left" of anything) and this mere right wingers in disguise imho. Im not from the US btw.

In the west you "promote hate" or "spread misinfo" or "are a Russian agent"; in China you "disturb the harmony". All ways to silence dissent if you ask me.
