One of the core tenets of the Libertarian Party is the Non-Aggression Principle (NAP).
This is the idea that “… initiating or threatening any forceful interference with an individual or their property” is inherently wrong. Based on the NAP, Libertarian thought derives the idea that one of the legitimate roles and responsibilities of government is to protect citizens from violence.
So what happens when you say that you oppose violence directed at others, but then turn around and say, “… but an unborn child isn’t really a person, so violence against them is acceptable.” ?
You’ve sacrificed your principles for convenience.
Is it any wonder, then, that people don’t take Libertarians seriously?
That they wonder what else we might give up, when push comes to shove?
Because principles do matter.
