It's a general framework with individual liberty at the core. It allows for a lot of different positions. It's not uncommon for libertarians to disagree but for different positions.
Yes there are factions of it just like other parties, but the core is that ideas are good if they don't infringe on other people's rights. Making a law which compels someone to provide a service to another is anti-liberty and most libertarians would not support it. Even then, many might support that measure at the local level because state rights is a big component and democracy is respected.
Anyway, what I like about libertarianism is that it provides a framework which is basically the Constitution at the core. Republicans and Democrats have no framework in how they go about things and we're in a big mess at many levels. There's been very little leadership and vision. If you look at what the two parties have done over the last few decades - they aren't that much different in practice and people are getting frustrated.
