Note that I do not think we were doing that badly before Trump and other authoritarians. It's just that a lot of people perceived the world was getting dangerous for them (probably because it became more inclusive, and also because they watch Fox news).
Or authoritarianism is a reaction to the perceived failures of (classical) liberalism to counter modern realities that are perceived as challenges because it suits would-be authoritarians to present them that way.
If you're on the left, I'm talking about immigration, and if you're on the right, I'm talking about climate change...
And really if by critical theory’s definitions that everything is relativist then what’s the problem?
Classical liberalism can under attack from critical theory over the last 40 years and has manifested in mainstream adoption of this type of thinking. This betrayal and dismissal of classical liberalism has forced the right into authoritarianism as the norms of liberal democracy have been dismantled.
