You've admitted to the things that the Libertarians do wrong. What if YOU were in their meetings, helping to develop policy and pointed those things out? If a handful of people, thinking like you do, influenced their policy, what do you think could happen?
The Libertarian Party is overran by fascists. They have no tolerance for people promoting libertarian positions. For example, their support for government licensing same-sex marriage. SSM provides not one iota of liberty to any homosexual. SSM only serves to promote tyranny, as a foundation for anti-discrimination laws and the use of tax dollars to promote a lifestyle which is abhorrent to a significant number of Americans.
Not one iota of liberty... except in the Orwellian sense as Libtards have redefined freedom -- forcing others to let you rape them, figuratively speaking. Practically every major platform position of the Libertarian Party in the past presidential election has the practical result of promoting tyranny.
If I went to their LP meetings, I'd be booted. Like violent antifa pigs, they'd accuse me of hate and intolerance, blah blah blah. They even boast of their website, "Libertarians say marriage equality only one step toward ending legal discrimination..." Uh, discrimination is liberty.
