A real libertarian knows that the basic unit of life is the Individual. That respect for the Rights of the Individual come first. Killing a human is by definition murder, regardless of if that human resides in the womb of another human.
Anyone who tells you otherwise is either lying about being a libertarian or has never thought the calculus through.
Or, is trying to paint us all with the same brush to further their own anti-freedom agenda...
Obviously, a “real” libertarian is a libertarian, meaning pro-abortion, like they are supposed to be.
