I have personally known women who were raped, became pregnant and kept the baby. But that is beside the point, this is an absurd argument that has been put forward by the pro-death movement. The number of women we are talking about is totally insignificant to the total number of abortions. Less than one percent of rape victims become pregnant, even if all of them choose to murder their baby (and let's try to remember that it's THEIR baby too, not just the rapist's), we still have 99% of 1 MILLION plus abortions a year that they pro death movement cannot justify.

However, when I see a poster drag out that tired old fish, and try to emotionalize it even further by positing the hideousness of bearing a rapist's child, I like to post that picture of the beautiful Lee Ezell and her beautiful daughter, who could almost be her twin.
Might make 'em think twice about that argument.
