I'm a conservative Republican. Emphasis on conservative, because we all know that very few Republicans are actually conservative today.
In my estimation, Libertarianism is not a pioneer's political viewpoint. It's a combination of some of the worst aspects of both political parties and a very old concept that many young people are embracing today because they think it's a viable alternative to the two-party system of usually partisan politics.
Our constitution was to limit government for sure, but it wasn't to eliminate it - or our founders would have never started one. From my interaction with libertarians over the years, if they had their way, they would eliminate it altogether. This is not the answer.
It might be the answer if men were angels and always did the right thing with freedom, but since they are not, no government or extreme limitations on government isn't the answer either.
James Madison made it clear we need a strong but limited government. If this were not the case, he and our founders would've never replaced the articles of confederation - which were already giving evidence of breaking down - with our current constitution.
Although Libertarianism is made up of a variety of personal beliefs, I find it a little more than coincidence that the party is made up largely of secular thinkers and atheists. This is consistent with wanting no or extremely limited external government controls on your life.
A man who wants no or extremely limited external government restraints, usually also wants no inward spiritual restraints. Or, they want or need extreme governmental restraints due to the impact the moral vacuum of their spiritual principles have created in culture.
This is precisely what's unfolding in Europe where government control has increased in direct proportion to the secularization of Europe.
In closing. From my perspective, Libertarianism is more about selfishness or narcism and an extreme independent " Don't tell me what to do because I don't want to be told what to do " attitude, more than it is whether or not it produces a stable, civil, and productive society for all of us.
It conflates " Freedom " with licentiousness and anarchy. Freedom is the guise by which it's promoted, not the reality upon which it's established. I probably have more in common with libertarians than I do Liberal Democrats. However, Libertarianism is not without its philosophical problems.
