Mostly irrelevant links. At least your last one mentions that...

Libertarianism celebrates things such as individual liberty, (...) individual responsibility, (...) and a free society.

Which is cool I guess, but it failed to show any examples of Libertarian individuals, or libertarian communities actually upholding that trait. I'm sure almost every ideology claims personal responsibility as a core value in some of it's foundational literature.

Typically, when I hear Libertarians talk about "Personal Responsibility" they tend to take it more "personal" and less "responsible".

I'd call it a weak source at best, but thank you for making the good effort to provide it. I really do appreciate it.
