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
Gustav Bauer had no religious affiliation and in any case he did not sign the Treaty of Versailles. It was signed for Germany by Matthias Erzberger, who was also not Jewish. But, those sorts of facts tended to make little difference to the German far right of that time which basically branded everyone they didn’t like as Jews.
