My answer?
I think it has a lot to do with the fact that women actually have babies.
A woman's experience with babies will have a lot of influence on her opinions on abortion.
Yes, there are some women who think: pregnancy is so hard, I would never impose that on a woman!
But most women come to realize that a fetus is a human being, and that abortion takes a human life.
When you've had kids, you can no longer deny that abortion kills, especially at the latter stages.
And I do think the columnist is right in saying men tend to support abortion because it gives them an out.
