"Ideology of Communism has some similar features:exporting socialist revolution (which can be equated to expanding the ideoligically friendly space), superiority of one social group (proletariat), annihilation of class enemies and their minions." Nope. There is no equivalent in Communist Ideology of My Kampf. Nazism is quite unique in this (well, excepted of course the main 3 monotheistic religions, and probably the polytheistic as well, but I am not sure of the last ones).
