First, libertarians seem to enjoy attacking other political parties specific positions while taking only a rhetorical one themselves. This feeds into #2:
Second, until the libertarian party actually puts together a platform, they aren't a real party. The reason's simple: first, nobody can tell what they're really voting for in terms of deltas to the legal codebase, and second, without going in with a plan, I don't think we'd even get the libertarians to agree with each other for doing anything.
To sum it up, I haven't seen a political party that's taken a real stance, but would rather sit on the sidelines and throw stones. Call me when you have a platform, not rhetoric. I don't want argument, I spent 11 years in a college town -- I've done it to death, I want actual proposals that I can personally evaluate. Until then, all I hear is ideology, and that's the last thing I want in government.
