Considering SU later become net subsidizer of Eastern Bloc, and that these countries were in pretty good shape right after SU dissolution, with all the limitations of "socialist economy", one-sided interpretation of history as exploitation, plunder, and atrocities and nothing more, sounds to me extremely stupid and narrow minded. As stupid as "killing his own people" meme. I'm disgusted by people who do moral interpretations of history with today's dominating moral standards. "Let's not forget atrocities of Roman Empire, plunder, enslavement, domination, exploitation of neighboring peoples ." Whole world history is one big atrocity.
Also, people who consider Soviet Union, a primitive oriental despotism, as a communist regime, without quotation marks - have no class.
