On the "Yeah, but that Wasn't Real Communism" Leftist Bromide

To a degree they're of course right (the fact that in true Marxism the state would eventually fade out) but do these imbeciles actually believe that in their utopian call to arms (just a figure of speech - relax) there wouldn't be a Stalin, a Mao, a Pol Pot, a Che, etc. lurking in the bushes and all too willing to put a bullet in the back of their skulls and give us the type of "inauthentic" communism that we've all grown accustomed to over the past, you know, 100 YEARS or so?......Sadly, they apparently do.
