I would say my biggest gripe with libertarianism, is it's a utopia, a fantasy...it doesn't exist
So when arguing with a libertarian and they make an argument for X, but there is no basis in reality that it could happen or that a lot of people would suffer due to the change
it's a great idea, but it's not a fact that if gov't stepped away things would be soo much better
I think in general its a very selfish attitude and typically only supported by people don't want to pay taxes at all
Now with that said, I like a lot of libertarian ideals and think we should work towards that...
