Speaking to this point, yes absolutely, people should stop mythologizing and elevating Hitler. He was somewhat effective at garnering media attention and knew how to utilize institutions to glorify himself and the party, but in most respects he was a terrible leader. I guess he had success in not being murdered by the Wehrmacht, though, which shows some competency at being a dictator. However, killing dozens of millions of people aside, his solution to the economic problem was massive Keynesian spending on worthless junk, like an autobahn in a Germany where there were very few automobiles at the time, funded entirely by extreme debt. Like, Germany's debt at the start of the war was proportionately as high as the United States' was after the war, which was astronomical.
Broadly speaking, people tend to search for simple causes, and for a situation like Nazi Germany, there were many causes. Pinning Hitler as responsible for Nazism is like pinning Trump for the alt-right.
Nazi ideology is, and I say this seriously, stupid. Not as in, "oh boy these people have low IQ", but as in, Nazi and fascist ideology deliberately has to eschew knowledge of economics, politics, history, and science. The first response to "Make America Great Again" should be "What historical circumstance are you looking to recreate?" Trump's great America doesn't exist. It's true that some things existed in the past which were better. Some were worse. History is, again, complex and multifaceted. We've talked about it quite a bit on here, but the biggest factor in the U.S.'s economic success in the mid 20th was because the rest of the industrial world blew itself up. How do you bring history back to that? Seriously, ask yourself what does "Make America Great Again" actually mean in terms of policy. If you find it vacuous and empty that's because it is, it rips out whatever little bits of history it wants, stirs them up and packages it to resentful, racist ****s.
And it was the exact same with Nazism. Hitler's vision was to restore Germany to a bygone age of pure, happy Ayrans living in a Bavarian dreamworld. Like Trump, Hitler pulled whatever little facets of history he could - anything that was liked, he tried to paint himself as the person that would restore that. No coherency or actual history needed. Nazism is stupid.
