You're missing my point ...I'm sorry but this is messed up. At least say "point of viability". Passing through the birth canal is a bizarre measure of "life".
"It cant survive, period" is at least somewhat defensible whereas "it can't survive without assistance" is murder. If you kill a baby that could be removed from the mother and still survive by other means then its just plain old murder.
Do we need a law? Or can we just trust women more than the state? That's the point!
Again, same argument Progressives use against guns. They don't trust people with self-defense. I trust people more than the state.
That's what it is to be Libertarian. I'm Pro-Life BTW, but also Pro-Choice, because I trust people more than the state.
