Libertarians are plenty frustrating. That's why the saying "it's like herding cats" is a true one.
The biggest one is this dumb battle over if Gary Johnson is a "real libertarian" or not or doesn't follow the principles 100% (like most really do? Yeah, right.) "No True Scotsman" in full effect!
Abortion being a divider. Should just remove it from the platform and not even discuss it because one part of the libertarian movement or another won't agree. When a question is posed just preface that this is your personal opinion.
To be fair, the abortion statement in the platform is honestly pretty neutral. Republicans/Consitution Party is all "You're killing life!", Democrats/Greens are all "Pro-Lifers are heartless/sexist/terrorists (Hillary has actually said that last one)", The libertarian platform on abortion is essentially "Government will do nothing because we have no idea what the right thing to do is."
