Hitler was Marxist in his rhetoric but only because that suited his agenda to win over the German working class. The full name of Hitler's party was the National Socialist German Worker's Party. This crude propaganda device, among well-known others, fooled enough Germans to give Hitler a plurality in the 1932 Reichstag. But once in power Hitler was profoundly anti-Marxist in his actions.

Marx may have been German but he was also Jewish and Hitler would not accept the beliefs of any Jew (most notably Jesus of Nazareth). Hitler hated socialists and socialism. He hated communists and communism even more. German socialists and communists vigorously opposed Hitler's rise to power and it was only divisions within the German left that allowed the Nazis to rise to power. Before 1933 the Nazis violently intimidated Germany's socialists into silence and after 1933 German socialists and communists filled Germany's jails until the concentration camps were built.

Again, despite his Marxist rhetoric, Hitler quickly and naturally made an accommodation with Germany's capitalists. They clearly saw his Marxist rhetoric as the sham it was and they supported his rise to power as a useful bulwark against the threat to them posed by German socialists and communists. Hitler reciprocated by crushing the German trade union movement while leaving German corporations unscathed. This belied any claim Hitler ever made to be a socialist.

Finally, the elephant in the room that you conveniently ignore, is that Hitler's blind hatred of communism as a Marxist and Jewish conspiracy led him inexorably to war with the Soviet Union. Exterminating Jews, Marxists, communism, and enslaving the Slavic peoples were the centerpiece of Hitler's agenda of promoting one people (Aryan) and one culture (German) united under one state-sponsored value system (fascist).

The fascist dream of promoting one people and one culture united under one state-sponsored value system dies hard. When Ann Coulter spoke of forcibly converting the world's billion Muslims to Christianity, she earned the right to be called an American fascist. To deflect attention from this wing-nut agenda, the polemicist Jonah Goldberg tried to pin the fascist tail on the leftist donkey with his book "Liberal Fascism".

Now, I'll credit Goldberg with being too smart to be taken in by Hitler's words but Goldberg didn't extend that courtesy to his readers. As for your own tendency to take Hitler's and Goebbels words at face value, well, a lot of Germans made that mistake exactly as Hitler and his propaganda minister intended.
