Considering it's women who carry the child, I think the sex of the debator is highly relevant. It's so easy for men who rape these women to say. And for men who aren't going to die because of an ectopic pregnancy.
All right, the position may be easier for men. However, I highly doubt rapists are opposed to the killing of their offspring who result from their crimes.
But I still say: To the debate itself, the gender of the debaters is irrelevant. If you are honestly debating whether it is acceptable to kill a child because his father is a rapist, or closely related to the mother, the debaters' gender doesn't matter.
