Having had some exposure to China/Mao's Cultural Revolution, I see so many similarities. Extreme political-correctness, attacks on common sense and tradition, pursuit of an illogical, unscientific, random, and above all, politically-constructed ideology, and resulting confusion, dismay and rancor among the population.
Our advantage compared to China is that while our central government has co-opted or stolen much control from civil society, it does not control everything, as the Communist Party did in China.
Yet nonetheless, America's own mindless cultural revolution will only end with some event that upends America's elite and status quo. My bet is on a major financial crisis that destroys our massive Federal Reserve and US Gov't debt mountain, which has been the grease for slide into national political insanity.
A massive EMP might work too.
