/r/Libertarian has gone through a few cycles of binge and purge since the halycon days of Ron Paul's '08 run.

The modern incarnation is more hostile to the GOP than I've ever seen it, and more flirtatious with leftism than its mods would care to admit.

Aside from all that, it's still an excellent place to bang heads for no other reason than its mod policy has (almost) always been incredibly loose. You'll get banned in every sub - from /r/neoliberal to /r/conservative to /r/shitliberalssay - for voicing half of what you've got a mind to on the Libertarian sub.
