Well apparently you don't because you made the claim that Libertarians protect the military industrial complex which, in of itself, is an outrageous claim. Considering Libertarians are some of the most anti-war, anti military people you will ever meet, it's laughable you'd even attempt to claim we support the beast that is the military industrial complex. Right off the bat, you've discredited yourself entirely by making that statement.
It's also pretty funny that you claim that Libertarians support the rich and powerful considering we are vehemently opposed to corporate welfare, bank bailouts, and corporate/bank subsidies. In fact, Libertarians have been in opposition to even the "anti rich" Democrats on these issues. I put "anti rich" in quotes because Democrats are even deeper in the corporate profit than the Republicans, which is saying something! Libertarians are extremely anti-corporatist, to say otherwise once again shows an extreme lack of knowledge of even basic Libertarian principles.
So, I will ask the question again. You have no flippin clue what libertarianism is, do you?
