Most people are libertarians at heart. FIFE can introduce them gently to libertarianism without the hard political edge of the Libertarian Party.
FIFE can act as a clearinghouse organization for libertarian groups of all kinds.
Freedom socials hosted by local FIFE representatives can distribute literature from various organizations. Few people are now or will soon be hard core libertarians. Many people already believe that the path to a better world is generally the path of less government. FIFE can reach out to these people the hand of friendship. Unless the LP changes a great deal, which is unlikely, this creates a niche.
