Right-libertarianism refers to a faction of libertarianism that strongly identifies with self-ownership, the non-aggression principle (it is immoral to initiate acts of force against persons or property) and free market capitalism while holding the idea that socially conservative policies are the best, even if they are only enforced by the various states in the United States. Right-libertarians differ from other libertarians who consider sexual immorality, prostitution, drug abuse, and other immoral things to be exercises of liberty, though may differ from conservatives in how these behaviors are controlled or prohibited.
