The reason I find it difficult is that I cannot get my head around the idea that some people think a woman should be forced to bear a child against her will. That this is still a debate in our country is to me the most blatant illustration of women's lowly status. Honestly. If some guy can overpower me and leave me pregnant against my will, and then the state can force me to bear that child and spend most of the rest of my life caring for it, then, am I really any better than a slave? I don't think so.
So I'm pro-choice.
Incidentally, I don' t know much about the Freakonimics books or their authors, but I happened to flip through one a couple of months ago and came across a chapter contending that the reason for the sudden, precipitous drop in the crime rate in the 1990s was down to the legalization of abortion. They linked the low incidence of crime to fewer unwanted children growing up to be criminals. So, you know, if just actually granting women sovereignty over their own lives isn't enough for you, there's lower crime to boot. But the sovereignty is enough for me.
That's all. Below is a nice story. Go read it.
