Hey SWJs (social justice warriors), check out this history of communist China:
Horrified by images of American students shouting down and physically attacking speakers on their campuses, some commentators have reasonably invoked memories of the Chinese Cultural Revolution. The problem with that analogy is that it is simply lost on most readers, including most younger than middle age.
So what exactly was this “Cultural Revolution” thing anyway? The U.S. media does a wonderful job of recalling atrocities that they can associate with the Right, while far worse horrors stemming from the Left vanish into oblivion. In reality, not only does the Cultural Revolution demand to be remembered and commemorated, it also offers precious lessons about the nature of violence, and the perils of mob rule.
In 2019, Communist China will celebrate its seventieth anniversary, and in that short time it has been responsible for no fewer than three of the worst acts of mass carnage in human history. These include the mass murders of perceived class enemies in the immediate aftermath of the revolution (several million dead), and the government-caused and -manipulated famine of the late 1950s, which probably killed some 40 million. Only when set aside these epochal precedents does the Cultural Revolution of 1966-76 seem like anything other than a unique cataclysm.
Emphasis is mine.
This lesson of insane mob rule is also a prime reason to own firearms and how to use them for self defense.
