It's pure Darwinism - wanting to make sure that you have as many off-spring as possible.

A pro-choice culture limits abortion naturally. When it's one choice among others, it's going to be one of the less popular options. While I disagree with Helen because some women do make a point of being casual about abortion they're not in a majority.

A pro-life culture increases the risk to everyone. Without choice, you're stuck with a child you may not want, may not be equipped to parent maturely, and may even have been forced into.

This is great news if you're a man, because you can be sure that women will carry your offspring to term and most likely be mother afterwards.

But the end result of a culture with those values is brood-slavery for women, and insitutionalised sexual abuse. A fundamentalist cult was raided a few months ago, and that's exactly the life style they'd created for themselves.

Specific pro-lifers may be appalled by that possibility, but even so - that's the direction their view pushes the Overton window.
