That setting up a tough turf to play on if you’re a pro-life libertarian. It could easily go:
Progressive: Well, you’re pro choice on everything else but not on the right to choose?
Libertarian: I’m pro individual liberty. You don’t have the right to take the life another individual.
P: Why not?
L: It infringes on their rights.
P: …Just like your pollution infringes on mine.
