The problem is the word libertarian has been used as front. That's because it has some good ideas.
Personal responsibility is powerful perspective when taken correctly, it has the power to move one's life in the direction they choose. That's because it is always an internal choice and not one coerced by fear, shame, or apathy. It's an unprovable event to any other individual, though one can testify. Considered an expression of self-compassion and is part of the practice of developing compassion for others. A perspective similiar with Buddists. Oh, it is also known to be closely related with forgiveness. Told you it wasn't political.
But used as front, a surface concept of personal responsibility is considered and it is used as an indicitment of others, as well as, personally asserted. Indicting others for personal responsibility political is a mistake and conceptually impossible. And what's missing? That is the depth.
Libertarian thing has also been used as a front all over and with different labels. Hard to tell the difference between a tea party, a libertarian, some conservatives, some republicans, some independents, ACISTS WAT WAT, something else, and so one.
This is why I think over time the libertarian thing has grown so distorted and dilluted. Some of it is a front. Some of it's key concepts are logical and language fallacy and others are incomplete or misapplied concepts used for indictment rather than understanding.
Another thing is the value of making generalizations about libertarians is diminished. It cannot be clearly tied to the party platform because other fronts deviate into different power circles. This made it a good front until it got pinned down by the idea police.
IDK Probably confirmation bias but more freebirds who don't prefer to identify as libertarians, but try to live that way, than people who call themselves libertarian at this point.
Oh, That's another good thing about personal responsibility. Just being aware of the notion can lead a person to develop it in a meaningful sense. Even as a bad front it can still encourage the value, just not too bad a front. No point having personal responsibility on a polluted starving planet.
