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 recall he blamed the original surrender of Germany in WW1 on the Jewish people because the main signatory was Gustav Bauer, the chancellor of Germany who was Jewish.
