Marxism has as its end nothing short of reshaping the way people think and behave. It is not the celebration of the individual, but the primacy of the community. Those that resist are eliminated. Of course, they never mention that little transition phase between what exists and the glorious future.
When you take a look at Nazism (a variant of fascism with a racial overlay), you'll see they're remarkably the same (putting the group in front of the individual). So, why is Marxism acceptable and Nazism isn't? Hell, Anita Dunn said one of her favorite philosophers was Mao Tse-Tung, and she wasn't run out of town on a rail. Could you imagine if Karl Rove said one of his favorite philosophers was Adolf Hitler?
I hate both, but am amazed that Marxism isn't just as shunned. And that's the point of the piece. Marxism has caused more human misery simply because it has been allowed to continue. If Nazism is worth driving from the face of the planet, why not Marxism?
