Here is a look at the observations made by a correspondent for The London Observer who compared the two dominate tribes found in 1933 Berlin and Moscow. The writer was far more distracted by the similarities in their street hustle and their sloganeering rather than their shared visions in governance and culture; for example, both Nazis and Communists were attracted to restrictions involving speech, assembly and gun ownership while sharing an equal enthusiasm for May Day parades and the color red. Additionally, both totalitarians had their preferred dupes:
"Absolute ideas invariably demand victims; and the ruthless treatment which is deliberately meted out to Jews in Germany is closely paralleled by the creation in the Soviet Union of a sort of pariah caste of Lishentsi or disenfranchised persons."
Germany never celebrated May Day with public parades until Hitler came to power; May Day was made a national holiday and all employers were given the day off with pay.
