I became a libertarian in college when I took an economics class and an ethics class that both spoke of Ayn Rand. That was like 20 years ago. I still believed in government for roads, military and all that. Recently about 4 years ago the rabbit hole swallowed me. Went full fledged anarchist, in principle. Still realistic though, so if all the government did is build roads I can live with that.
War is the only thing I really focus on now though. It sickens me the idea that my kids can be sent by force to die in Syria if the government decided to have a draft again. With the way things are going I can see that happening, so I speak out for that.
