The scale of some Chinese people's commitment to support of their government's chosen narrative against facts is quite impressive / scary. Zealots make great cannon fodder, and the more cannon fodder the higher the chance of winning. It bodes poorly for Hong Kong, Taiwan, and any other country with a coastline along the South China Sea.
I used to think but the last few years in the US taught me that people everywhere have the same capacity for zealotry, they may have to be reached/triggered differently that’s all.
Plenty of groups of Western folks get super amped up over any threat to the continuity of their chosen self destructive, unhealthy, unsustainable lifestyles to which they've become accustomed. Because freedom!
