Ron Paul has said that he thinks some people are born libertarians and that he himself was born such.
There is an understandable natural tendency for life-long libertarians to agree with Ron's claim. I think he may be wrong.
If it is true that most libertarians are born libertarians, the libertarian movement is in a lot of trouble. At best, I estimate that maybe 5% of the population is libertarian. If you become a libertarian at birth and we have the percentage that are libertarians, then there is little chance we will ever see a libertarian society.
But, as I say, I do not believe people are born libertarians. I believe some people are born with a healthy brain balance between reality, logic and emotions (as contrasted with, for example, pathological altruists). That is, they do not allow emotions to interfere with their understanding of the real world. They recognize reality for what it is and don't try to emotionally block out clear thinking or go into denial about some things in the world.
Freedom and libertarianism are very logical things. If you have an open mind (no blocking mechanisms operating) and think things through logically, you are going to be a libertarian. But, it's the thinking logically, and having a correct balance with reality and emotions that people may be born with. Thus, it is very easy for such people to become libertarians early in their life. But it is the logical thinking that we are born with that begins the process, not an inherent libertarian philosophy.
I have talked to many adults who have only come to libertarianism in recent years. They all tend to be very logical, thus, it is not surprising that they would be attracted to libertarianism. In fact, most tell me that in the past, although they might not have been full-fledged libertarians, they had libertarian "instincts." To me this means that they likely were simply thinking logically about events and society without having a full libertarian perspective presented to them early on. That is, it may just be that while they weren't exposed to libertarian ideas at an early age, their logical way of thinking was always pushing them in that direction--always suspicious of interventionist and government propaganda.
Thus, if the key to being a libertarian is logical thinking and a healthy balance between emotions and thinking, and exposure to libertarian ideas, then there is a lot more hope for a libertarian society, since the number of current libertarians is certainly only a subset of generally logical thinkers. The more logical thinkers that can be made aware of libertarian logic, the better.
Further, many of those, who let emotions get in the way of their thinking logically, are always attempting to improve themselves. Thus, an introduction to the logic of libertarianism can be a step in their growth process.
In other words, I hope Ron Paul is wrong on the point of how people become libertarians but I hope he keeps on spreading the logic of the libertarian message, because he is the master at it.
