Whether your interest is in Aikido, Taekwondo, Wing Chun, Wushu, or Karate, (or any of the many established forms of martial arts) Libertarianism and martial arts go hand in hand.
As a practitioner of Taekwondo, one of the core teachings of martial arts, that is attractive and alluring to me, is the emphasis on self-discipline.
Every martial art that I've ever heard of teaches the discipline of utilizing your skill only when absolutely necessary; as in the case of self-defense.
This is a fundamental principle of Libertarianism as well: quite simply, don't initiate aggression onto others and defend yourself when necessary.
Many Libertarians are armed with intellect, reason, the capacity to argue valid points, principled adherence to philosophy and ideology, as well as being armed with a stockpile of guns and ammunition.
Martial arts is quite useful in situations where fatally injuring someone would not be the best solution.
The discipline of martial arts (emphasized strongly in martial arts such as Aikido) teaches that the minimum amount of damage inflicted, necessary to subdue a threat, is the 'honorable' course of action.
Although, the level at which you choose to defend yourself is ultimately up to you.
Another great thing about martial arts is mental clarity...
Political discussion can make people angry or emotional and martial arts is a good way to quiet the mind & restore equilibrium with oneself.
Martial arts philosophy is congruent with Libertarian philosophy in many ways. As such, I recommend that Libertarians learn a martial art.
The art and training will fortify the mind and body.
