Nazism was a leftist ideology

"Why should the German be interested in the liberation of the Jew, if the Jew is not interested in the liberation of the German?... We recognize in Judaism, therefore, a general anti-social element of the present time... In the final analysis, the emancipation of the Jews is the emancipation of mankind from Judaism.... Indeed, in North America, the practical domination of Judaism over the Christian world has achieved as its unambiguous and normal expression that the preaching of the Gospel itself and the Christian ministry have become articles of trade... Money is the jealous god of Israel, in face of which no other god may exist".
Who said that? Hitler?
No. It was Karl Marx. See also here and here and here. For roughly two centuries now, antisemitism has, throughout the Western world, been principally associated with Leftism (including the socialist Hitler) -- as it is to this day. See here.

The Leftist hunger for change leads to a hunger for control over other people. And they will do and say anything to get that control: "Power at any price". They are mostly self-aggrandizing crooks who gain power by deceiving the uninformed with snake-oil promises -- power which they invariably use to destroy. Destruction is all that they are good at. Destruction is what haters do.

Leftists don't have principles. How can they when "there is no such thing as right and wrong"? All they have is postures, pretend-principles that can be changed as easily as one changes one's shirt.

Above Quotes from Dissecting Leftism

Nazism is almost per definition an accusation against the 'right' but it is really part of the left's "projective" strategy - seeing in others what is really true of themselves and the very characteristics of the left.

I personally think that the definition 'Left and Right' in politics is outdated, in fact it goes back to the French revolution where the opposing parties were seated to the left and right facing each other - What is true to the nature of the collectivist totalitarian ideologies from the left instead of calling it 'Left and Right' the definitions should be 'Utopians and Realists', that explains in a nutshell what it really is about.

Nazism was a leftist ideology

By Henrik Ræder Clausen - EuropeNews

With some annoyance, I recently noticed my local newspaper, Aarhus Stiftstidende, full of articles about Nazism, an ideology I thought we had seen the last of on the 5th of May 1945, when Denmark was liberated after 5 years of German occupation. But it seems we're not that lucky.

A Nazi group exists in Denmark again, and leftwing extremists like Antifa contribute by putting up swastikas in the streets of Aarhus. While the craft was nicely done, it was swastikas nonetheless, a symbol I do not want in my city under any circumstances.

Then, there seems to be some confusion as to where Nazism belongs in the political spectrum. That is understandable, for probably no political group in Denmark (save the youth branch of Venstre, who recently held a meeting with them) would tolerate their company.

For this reason, it's important to make clear that Nazism (the full name of the political party was ”Nationalsozialistische Deutsche Arbeiterpartei”, which translates to ”National Socialist German Workers Party”), also according to their own understanding, is an extreme leftist ideology. They consider themselves to belong to the tradition of the Jacobins in France, and taking into account the Reign of Terror instigated by them, this is not an unreasonable characterization.

If one looks at the Nazi political program, and it's implementation during the 1930's (before the war), it was distinctly leftist, and radically so. Quoting Bruce Walker in American Thinker:

Vera Micheles Dean in her 1939 book, Europe in Retreat, written before the Second World War began, said that the Nazis had introduced into Germany a form of graduated Bolshevism, focusing first upon Jewish bankers, industrialists and businessmen, but then upon other businesses, noting that the Nazi goal, from which it had not deviated, was to establish an egalitarian society in which everyone is equal and subordinate to the state.

The main Nazi propagandist, Joseph Goebbels, made it clear from the outset that nothing was more despicable to the Nazis than the Bourgeosie, the Capitalists and Christianity. Any confusion to the contrary may be due to the fact that the German Conservatives, in a vain attempt to 'influence' Hitler, decided to eventually work with him once he rose to power. This granted him the legitimacy he so desperately wanted, the power he needed to fulfil his plans, while the utterly frustrated Germans lived to see him wreck total havoc in Germany and Europe at large.

For obvious propagandistic reasons, Stalin and his allies fiercely insisted on using the 'right-wing' label on the Nazis. It would certainly not look good to expose the fact that Communism of the Soviet Union seen from an economic point of view (anti-Semitism is a different matter), was merely a more radical variant of the system implemented by Nazi Germany.

After the fall of the Soviet Union, an exhibition in Moscow compared Hitler and Stalin to great effect demonstrated just how similar Communism and Nazism are in their totalitarian insanity. Many an old Russian, who through decades persistently had admired Stalin, left the exhibition in tears, after it had become clear just how similar Communism was to the Nazism it had defeated.

As for Nazism as such, it is a confused and foolish ideology that doesn't deserve life on earth. It is better to discuss issues of actual relevance.
