A vocal section of world socialism finds it embarrassing to admit that Hitler was indeed one of their brethren.
I understand why some have a problem. Among those are some that do not realize they are being used by their own.
You miss my point. Just because National Socialism has 'socialism' in its name does not make it 'socialist'; that is, derived from Marxist theory, any more than a Christian Democrat in Europe is Christian in any real sense of the word. Hitler rose to power at least in part from the financial support given him by the Directors of corporations such as Krupp and E.G. Farben, who did so because of their fear of the communists. They certainly understood a distinction between the two, and were no doubt hoping for an accommodation with Hitler such as the one Mussolini enjoyed with Italian big business.
And I don't mind being in a very small minority if I know I'm right.
