Overfocus on Hitler obscures the reality that antisemitism was the norm in the political culture at the time. Politicians with explicitly antisemitic platforms were getting elected before the Beer Hall Putsch even happened. If we step back from the man and look at the culture, there are poignant lessons to be learned and applied to the modern situation.
Article can be summarized as: by the time he moved to Munich he already didn't like Jews because he thought they were cheap and wouldn't pay a fair price for his paintings. That's unfortunately the only information available here.
There probably isn't any deep or interesting reason why Hitler hated Jews. Lots of people did back then, especially if they were socialist. It's much less famous, but Marx also hated them with a vengeance. He saw them as the personification of capitalism and believed that under communism they would be wiped out. From his essay "On the Jewish question":
"What is the worldly religion of the Jew? Huckstering. What is his worldly God? Money [...] An organization of society which would abolish the preconditions for huckstering, and therefore the possibility of huckstering, would make the Jew impossible [...] Money is the jealous god of Israel, in face of which no other god may exist. Money degrades all the gods of man – and turns them into commodities [...] The bill of exchange is the real god of the Jew. His god is only an illusory bill of exchange [...] The chimerical nationality of the Jew is the nationality of the merchant, of the man of money in general."
This sort of language was nothing special in that era. The association of Judaism with money making and capitalism goes back thousands of years.
Hitler was directly inspired by Marx so it's perhaps not a surprise that he adopted similar views. Hitler said in 1934:
"National Socialism derives from each of the two camps the pure idea that characterizes it, national resolution from bourgeois tradition; vital, creative socialism from the teaching of Marxism."
Technical question (half in jest, fully in earnest): Since the research and course described in the article is about how Hitler's radicalization may be analogous to current political radicalization and antisemitism, are we simply starting at the point where Godwin's law is already fulfilled, or does the corollary of Godwin's law still apply, i.e., "when a Nazi or Hitler comparison is made, the thread is finished and whoever made the comparison loses whatever debate is in progress"?
It still applies. Comparisons of current society to Weimar Germany are completely misplaced, and especially on the question of antisemitism. Attempts to do so are simply capitalizing on the fear of the moment.
