I am a very very lazy person. I like to pride myself on being in the running with Lebowski. And to me hate takes way way to much energy. Having even the simple idea of killing has to take some effort. Kind of seems like he just set out on a life not worth living IMO
I can’t be arsed going into detail, but I’ll give you a half-answer to get you started: “Negative integration”. It basically means that ones identity is based on who you aren’t as opposed to who you are. Ramp this up to 11, and you further this negative integration into defining who ones enemies are, and that’s a core tenet of how fascism takes root.
