All political parties are evil. The Libertarian party hasn't won a single significant election yet, but there's still infighting and hidden agendas within that party, just as bad as the Democrats or Republicans.
Same for the Natural Law Party, the Objectivist movement, the Bruce Lee martial arts field, or any other ideology-driven organization.
There are no political parties governing the Internet, and it is evolving fine. (OK, there are kinks, like the Spam episodes, but time is proving that majorities don't need political beauroccracy to make their opinions known)
My advice- do not ever sell your soul to any "complete agenda"-based organization. You can spend your life working hard towards a goal and see it wisked away, by your own people, in the blink of an eye for some internal compromise. If you want to make a difference, work for single, specific goals.
You can start with growing shrooms in your basement and giving them to friends. Once people are able to think for themselves, a lot of these petty arguments (abortion, politicians' personal histories, etc) will become less a front-stage event.
