In some conversational fields, men aren't supposed to voice opinions on abortion. If they do, their opinions don't count -- as if one has to have a uterus in order to figure out whether or not it's right to have a child killed for being inconvenient, for being imperfect, or for having a bad parent.
Regardless, all that having been said, I've always wished more of the anti-abortion-on-demand majority of women would be more vocal. I do grant that it has to carry more emotional conviction for a woman, who might (even if only theoretically) find herself in a difficult pregnancy, to make the case, than it does for a man.
I planned to post a pro-life essay on this, the occasion of the anniversary of the bloody Roe v. Wade decision. But I am delighted to be able to point you instead to a great post by the priceless La Shawn Barber, titled Blogs4Life/March for Life II. Read that, and La Shawn's Townhall essay Marching for life and against the "Negro Project" as well. Then, if you'd like to read a Biblical examination of abortion, feel free to check out mine.
