I am generally reticent to criticize people based on the era they were born in, and Millennials are no different. I know there are smart and conservative Millennials, but I will say this:
There seems to be (as the author states) a far higher percentage of young people who buy into socialism, Marxism, CRT, and political correctness than there ever has been before.
I believe Aristotle said that the young are full of enthusiasm for changing the world and that they were particularly disadvantaged because they have so little knowledge of it.
They buy into it because they can still afford an iPhone, MacBook and drink their craft beer. Life is easy for them and nary a one lives with any of the consequences of the ideology they choose to support.
