Whether you look at Chinese emperors, Egyptian pharaohs or Christian Kings that claim divine right, authoritarianism is part of nearly every complex society by design.
The West is the only complex society that slowly accorded the individual versus the family or the group strong inalienable rights. Only the British empire and its subsidiary nations stood up and said everyone gets these rights, ending slavery everywhere it could, saying you don't burn widows in India, freedom of speech and belief is universal.
Social justice warriors can be seen as authoritarian liberals, sharing the same authoritarian streak as Communists who say there shall be no institution or private associations that contradict sacred State doctrine.
These liberal bullies are on the rise because they've grown up in a strong thought bubble, never hearing contrary views, hearing that liberalism and only liberalism is good, moral, smart, rational, sane, love - so conservatives are stupid, crazy, irrationally phobic, stupid, ignorant or evil haters.
Hear the demonization of whole ideologies this much and reinforced on every front, of course you can join in violent mobs to shout down people and then, if they don't shut up, beat them up for daring to assault you with their evil hate speech. That is weaponized empathy, fascism wrapped in a mantle of warm feelings. That is where the modern liberal authoritarians attacking professors from Evergreen to Middlebury, attacking everyone else from Berkley to Vancouver come from. They are the angry revolutionaries their teachers trained, and liberals are only upset that their creations turned on them. They were supposed to attack everyone else.
