Even apart from religion AND biology, from a libertarian point of view, granting women the right to terminate a pregnancy also ignores the rights and interests of other parties involved. It reduces the man’s decision to next to nothing.

It’s to the advantage of pro-choice advocates to see the embryo/fetus as nothing more than a bunch of cells (aren’t we all???). If it is a unique human, abortion allows the rights of the mother to usurp those of the child.

Then the “right to life, liberty and the pursuit of happiness” goes right out the window.

As Chesterton said, “Fallacies do not cease to be fallacies because they become fashions.”
