You'd have to talk to a fucking psychologist to figure that one out.

But some people just decide that we need an all white, all Christians ethno-state, and everyone who doesn't fit in that category can leave, or preferentially, not be allowed to leave and kept as slave labor. I've already spent too much of my own life trying to convince those people that such an arrangement harms everyone involved, and recognizing different cultures, backgrounds, traditions, and life experiences makes you a happier and better person.

And yet they still join up with the proudboys and loudly proclaim that white western chauvinists built the modern world while everyone was trying to drag them down and ruin it.

Being a nazi shitfuck is a choice. It's a choice made in glaring defiance of human experiences that we all have every day. Unless they were literally raised in a nazi cult that forbade going outside the compound, then they've had a choice to stop being a nazi shitfuck every day, every hour, every minute, every second... And every time, they gleefully and repeatedly make the wrong choice.
