Hitler was significantly more educated than most modern progressives. From wikipedia:
He read newspapers and pamphlets that published the thoughts of philosophers and theoreticians such as Houston Stewart Chamberlain, Charles Darwin, Friedrich Nietzsche, Gustave Le Bon and Arthur Schopenhauer. Georg Ritter von Schönerer became a major influence on Hitler. He also developed an admiration for Martin Luther. During his time in Vienna, he pursued a growing passion for architecture and music, attending ten performances of Lohengrin, his favourite Wagner opera.
It is a fallacy that murderous racists are simply uninformed, that they just weren't in school on that day in the fourth grade where your teacher tells you to be nice to people. Some of the authors he was acquainted with were vocally against anti-semitism. The most dangerous monsters are highly educated people.
I take issue with every sentence you wrote. "Highly educated"? I don't think so. "Some of the authors" - you mean Nietzsche, I guess. It seems likely he didn't read Nietzsche's books, but just the bits quoted in (anti-semitic) newspapers. Check out Chamberlain and Schönerer. The first thing you notice is the strong Nazi-type flavour of their thoughts. Wagner and Luther are notorious for their extreme anti-semitism. That first wiki-sentence comes to "He read the paper". My understanding is, on the street corners and cafes of Vienna in those days were a dozen different half-nutty political groups, and Hitler took a bit from every one of them. The stuff was in the air, if you stopped to breathe it in.
