Out of curiosity, how many people are just now finding out they're libertarian? Really, I think most people, especially those who don't want to involve themselves in popular politics, will find they're libertarian; anyone who simply believes in being and letting be counts as a good person to me. The only difference is whether the person self-identifies as libertarian or not; considering the amount of dissenters toward the increasingly authoritarian America, it is quite easy to see, we at least generally agree that we don't want what's become.
The problem is that there's the libertarian "let people smoke pot if they want I don't care" and there's the libertarian "let people die in the streets if they don't have money to eat I don't care". The latter keeps most people from identifying with libertarianism.
That's not what libertarianism is about. If it was obvious that government was the solution to social problems then I would admit it, but this just isn't so. History shows that as governments get bigger and bigger they stagnate the economy and move closer to collapse. You look at the giant Western governments and the level of debt is staggering. Anyone thinking that that can last forever is insane and you know who's going to pay the price when the party ends? Hint, it isn't going to be the rich.
Libertarians are far more humane than non-libs in general because they understand how the market works and what set of circumstances leads to the greatest prosperity for the largest amount of people.
Putting your faith in government has, over the last century, proven to be the greatest mistake that individuals can make. There are so many countless millions of examples around the world of people who put their faith in governments to look after them who ended up poor, destitute or in the worst cases, dead.
