I consider myself to be a Christian Libertarian, also a Conservative constitutionalist and a traditionalist. You are making a fundamental mistake in associating the ones you claim to know with all Libertarians. There is more than one path to a political philosophy and that path isn’t as important as the destination. That destination is limited government and individual autonomy. From a strictly political philosophy point of view a man’s religious beliefs don’t interest me at all.
I’m not making any mistakes because I never said that all libertarians think the same way.
Libertarians are not social conservatives, Christians are.
