...but I tend to think that it has something to do with Germans being a minority in Austrian-Hungarian Empire. Mein Kamph indicates Hitler hated all other minorities, especially Czechs and Jews. The nomination of Czech priests into German speaking congregations was an example of Czech conspiracy... I believe many Austrians talked like that after one beer too many but it took a Hitler and a lot of coincidences to bring this c*#p to Berlin and Reichstag... P.S., in their early days National Socialists did not separate themselves so much from Russian Socialist Democrats (Bolsheviks). In early 1920ies Goebbels (!) wrote that Hitler and Lenin had so much in common, both were good speakers and great leaders... But affection remained, and Hitler learned a lot from Bolsheviks - concentration camps (Slava trudu - Arbeit Macht Frei), and the possibility of a large scale genocide (Ukrainian Holodomor) that was a revelation to him.
