> I'm still unable to process that people like Trump, Putin, Orbán, et al

I am sure you put these people in the same basket by no logical reason, as they are very different and the reason behind each of them is very different. As an Eastern European I understand a bit more Orban and Putin, I don't have to agree with them to understand how things work, and they the 3 have almost nothing in common but being targeted by the political left as the enemy.

> the 3 have almost nothing in common

Come on, you know what they mean. They're authoritarian populist leaders with a disregard for the rule of law. Cruel men that rejoice in the "destruction" of their political enemies both figuratively and literally. Men with little emotional control that suffer from severe anxiety at anything that doesn't fit their very narrow view of the world.
