1) Open borders are non-negotiable for libertarians, up to and including a nuke-equipped-RV-driving immigrant.
2) Open borders are non-negotiable for libertarians, up to and including mass invasion in unlimited numbers by "peaceful" immigrants whose stated purpose is to end libertarianism.
3) Open borders are non-negotiable for libertarians, up to and including mass infiltration by millions of troops of a foreign power.
FOUL! Every one of those scenarios violates the Non Aggression Axiom. I don't think any libertarian would accept them... except perhaps in some kind of distant anarcho-capitalist world where private nukes are common for some reason.
Bottom line... there is no way for you to prevent me from inviting my Mexican friend onto my property without violating my rights with violence.
Does anyone here actually believe that Skeptical is even capable of being swayed by a rational argument?
No. He lost me when he argued that libertarians would destroy tribes, cultures, ethnicities etc. because apparently those things can't exist without violating the rights of the individuals that compose them... or collectives have a right to exist greater than the right of the individuals that compose them to exist... or whatever.
The point is he claims to be semi in line with libertarianism, than says libertarians support genocide? If he's so far off that the NAP is not even part of his understanding he has no idea what he's talking about, and no idea how to process anything anyone is saying. It's a trap. He trouts out this bait, "I kinda like libertarianism, please explain it to me" than responds to perfectly reasoned explanations, which he doesn't necessarily have to accept, but could at least understand, with "You're stupid! You're like autistic or something and I'm smart because more people agree with me!" Classic trolling. Self esteem issues. Probably mentally brutalized as a child. What ever the case, life's too short, and it's not worthy your time. I suggest everyone disengage.
