I am slowly discarding my differentiations between stupid and evil, there’s a different, mysterious third thing that combines both but exists on its own.

Willful Ignorance. Choosing to remain stupid despite access to information.

https://bonpote.com/en/the-5-basic-laws-of-human-stupidity/

Law 1: Everyone always and inevitably underestimates the number of stupid people in circulation

Law 2: The probability that a person is stupid is independent of any other characteristic of that person.

Law 3. A stupid person is a person who causes losses to another person or group of people when he or she does not benefit and may even suffer losses.

Law 4: Non-stupid people always underestimate the destructive power of stupid individuals.

Law 5: A stupid person is the most dangerous type of person.

It's a combination of both. Stupid people stuck in echo chambers being brainwashed and manipulate by the evil people. 

At some point I’m not going to care if the punch you’re swinging at me is from ignorance or not. I’m still getting hit and I’d be stupid not to defend myself.
