You get to wear a brown shirt, black tie, armband, doc martens and raise your arm in salute. Nobody asks if your going bald because you have shaved your head. You get to hang out with white supremacists and other interesting people. What are the drawbacks of nazism?
Hitler himself was incapable of accepting that Germany was losing until the very end. If I remember correctly he even left a letter that encouraged his people to fight on. No one really knows what diagnosis Hitler had. A post-war assessment of his mental health, declared him to be a "neurotic psychopath". So how was Hitler as a person? Artistic and a charismatic speaker but also lazy. When he was a painter, Hitler's Jewish agent had a hard time getting him out of bed to paint. Another painter was Churchill, whose style was so similar to Hitler's that people can't tell their paintings apart. I can though and I even did a test to prove it. So Hitler lost which resulted in among other things, the Jews getting their own state and the multiculturalism of Europe.
