Nobody is hating on you, just expressing disagreement with a sloppy argument. I understand without fully sharing your view of government as seriously antiquated, but then you blew any credibility you had by throwing in 'marxists' as an insult. This is no more credible than a bunch of leftists trying to shut down an argument by making an umbrella insult of 'capitalists'.
Marxism strikes me as an incomplete and therefore flawed socioeconomic theory, but all other economic theories have glaring deficiencies of their own. Capitalism works very well within limited parameters, but has glaring faults of its own, and market fundamentalists are capable of being just as blind and pigheaded as any Marxist I've ever encountered. We don't beat up on Adam Smith or David Ricardo despite the incomplete nature of their economic insights. Serious economists, including conservative ones, take Marx seriously without necessarily buying into all his ideas.
