If all you have available to "give" are poor imitations of intelligent debate,
For a group of people who love throwing around words like, "Marxist" and "Tyranny" and "Collectivist" and "Fascist" and "Moochers" and "Leeches" and "Parasites", I'm not sure you're in a position to judge what is and what is not intelligent debate.
Yes, what passes for a libertarian in 2014 is a thin-skinned mental undergrad with a grudge. A Republican who read once read a book. Any push back at all and they holler, "Mom, he's hitting me back!" Bitter and brittle, they march around just knowing that society could be so wonderful and free...if only. Protected by the notion that they'll never have to actually perform. And whenever libertarian policies are put in place, the resultant failure is always blamed on not having gone far enough. So, if only they had really gone a few steps further, it totally would have worked. In that way, they are just like the handful of hard core communists left. "If only they had really gone all the way with libertarianism/communism, it would totes have worked". It's actually a lot like your basic extremist follower of any other New Age belief. "The coffee enemas would have cured their cancer, but they just didn't stick closely enough to the regimen." Or, "The faith healing would have totally worked, but the patient didn't have enough faith." It's an argument that can never be won, which is why most people have given up and have just taken to ignoring them.
There is a reason no society in the world, in history, has ever tried to fully implement a fully libertarian system. Because even those most desperate for liberty - especially those most desperate for liberty - can recognize full-blown crazy when they see it. But I have to say, it would be a great treat to see a libertarian live for one day in such a society.
There's also a reason that of all the times the John Galts of the world have decided that they're going to create some floating libertarian utopia somewhere beyond the evil grip of the choking fist of government around their skinny necks, it's never ever happened. Because in the marketplace of ideas it loses every single time. Even libertarians know the idea is crazy, but they've become in love with the vast amount of self-regard that such a philosophy affords them, safe in the knowledge that they'll never be called upon to actually, you know, live like that.
