I too differentiate
strongly between libertarian & Libertarian.
I gave up on the Libertarian Party back around 1986, when I realized how much rhetoric they were using from poorly remembered Ayn Rand articles & hoary John Birch Society cliches.
I worked at a newspaper. One of our reporters came back crestfallen because he'd covered a campaign stop by an LP candidate, & this reporter considered himself an LP supporter. Well, after a rousing speech, the candidate went around the room shaking hands... & right near the reporter stopped to tell a racist joke & have a laugh with a few supporters. (Let's just say "N-word.") This sorta imploded the reporter's understanding of the Libertiarian Party.
And as much as I would like to see an actual functioning Free Market Economy -- after all, that's about as Socialist as you can reasonably get!!

-- the cold nasty fact is that
THE FREE MARKET IS AN OUT-AND-OUT LIE, designed for the ultimate victory if the biggest, nastiest, most egocentric players. Anyone touting it is either a fool, or a liar, & there ain't no third option.
Now, given all that, since 1986 the LP has further been taken over by "reasonable Republicans" & crypto-anarchist teabaggers.
In Wikipedia, Gary Johnson said in 2012 that the LP is (quoting the article, not him) "more culturally liberal than the Democrats." They're anti-censorship (to the point of being pro-porn), pro-queer, pro-drug -- none of these seems to get mentioned much in public.
However, they believe that with no government oversight & no taxes with which to maintain credible enforcement of the few remaining laws, the citizenry will fix stuff all by themselves. In my reading of world history, this is almost always solved by the rise of warlords, dictators, the Chicago Mob, etc. -- leadership by one or a few Glorious Leaders protected by sadistic thugs -- rather than the anarchistic oligarchy the LP promises.
A few authoritarian regimes to examine.
Add in that the solution for problems with the public school system will be solved by the Free Market... the environment will be protected -- nay, improved!! -- by the Free Market... roads & bridges will magically be repaired without ANY tax money by the (sing along with me!) Free Market... the poor & underemployed & disabled & elderly will all receive proper healthcare thanks to the (lalalalalalla!!) Free Market... a woman's right to seek safe abortion will be protected by preventing The Government from keeping the clinics safe & funded -- yep, there's that Free Market thing again...
The abortion thing didn't even occur to me, until I read an article by LP icon F. Paul Wilson, where he stated plainly that abortion should be outlawed in order to protect the personhood of the mass of cells often called a "fetus." That's where factions like "Libertarians for Life" crop up. And as for the Free Market solution:
Recognizing that abortion is a sensitive issue and that people can hold good-faith views on all sides, we believe that government should be kept out of the matter, leaving the question to each person for their conscientious consideration.
Anyway, the LP is at best a one-trick pony, with one Grand Unifying Theory that they claim will fix Absolutely Anything. (And since it's impossible, they ain't got even ONE trick.) Their constituency has changed since they left Colorado, & I can't see where it's for the better. Sure, maybe the GOP has intentionally stirred Right WIngnuts into the LP to keep it from becoming a standalone threat, but the damage is done.
