Nature of Antisemitism

Antisemitism is just hatred of capitalism.
The Nazis suggested that the Jews were in control of all the major banks and basically pulled the strings, making them the symbol of the wealthy elites, the banks and businessmen with a disproportional amount of wealth and power. The Jews were the very symbol of internationalist imperialism. Ask the leaders of the old left-wing radical groups such as the RAF.

The Nazi party itself might not have been leftist, but it certainly started out that way. They even retained a touch of socialism even as Hitler took charge, purged the commies from his party, embraced corporatism and bent over backwards to receive funding from big business. I think that is what people mean when they say "Hitler was a Jew".

Back then, just like today, the war was not between left or right, white or black, rich or poor, but between nationalism and internationalism.

What is the psychology behind bigotry anyway?
Usually a superiority complex based on the (subconscious?) realisation that one's own life is made of suck and dipped in fail on at least one level. However exactly what level that is (or if they realise that, or if they're even right about that in the first place), depends on the individual bigot.

And so the need for a target. That usually means an easily-singled-out group that one can project one's own shortcomings on. Again, the exact details depend on the individual bigot, but this is the basic underlying principle.
