So it's pretty much universally accepted currently that Adolf Hitler and the Nazi party are evil. You can show a swastika to a 12-year-old and he'd probably be able to tell you that it's the symbol of one of the most evil reigns of government ever conceived in recent memory. However...
How do we make old spiteful Adolf a little less...belligerent? Say, for instance, that Hitler still goes through his normal actions of attacking Poland, being a hot head, etc...but the only exception between our history's Adolf and this Adolf is that he doesn't preach for antisemitism or for the "eradication of lesser races." No Holocaust, let's suppose. Maybe he even develops a platform on plurality and openly tries to encourage the acceptance of minor cultures and faiths, maybe through gradual (or forced) assimilation (but not through mass murder). Would he be "revered" in Germany to this day if this were the case? Could he still have seized as much power as he did without his hateful rhetoric, or would this be butterflied away? Also, if his speeches and government platforms were thus less hateful, would this likewise butterfly away the Sudetenland, Memel, Austria, remilitarization, etc? Is it still possible to be a fascist/national socialist and "multi-cultural" or is this value completely incompatible with the idea?
