I don't disagree, but from my experience Libertarians tend to live in a fantasy land where reality can be ignored and everything is made up. So there is nothing really to be learned by attempting to communicate with them, aside from more curious facts about their ideology.
I enjoy discussing things with people who believe different things from me too, but if those people base everything they believe and say on a super faulty ideology that doesn't at all jive with reality, then disagreeing with them and trying to work out through the disagreements is usually not going to be worth it. It's just going to lead to frustration, really. You're far better off discussing things with people who agree that reality is something we should consider when making statements about reality.
Anyway, back to the issues men can face. The biggest right now for me is that we can't even seem to be able to discuss these issues and try to address them. People will jump out of the woodwork and start shouting you down no matter what you say.
