The mother is the one who has the baby and who has the abortion. I think everyone agrees that it would be ridiculous to let just the father decide- If the mother had no say and the man got to pick, then he could make her do things, i.e. get an abortion, that she didn't want to do. So why should he get to help at all? If he were pregnant, then he could pick.

If it was mandated for both halves of the parental unit to sign a consent form, what would happen to women who had been raped? Would they have to wait until someone tracked down their rapist, and then only get an abortion if he said they could? And as for women subject to incest or familial rape, who refuse to name their rapist because they are related, would it be fair to refuse them their abortion rights? It is, with out a question, the women's choice, and the women's choice alone.

Personally, I don't believe in it simply because it feels dangerous, like if he actually did exist I would be in trouble. That's part of why I don't believe- Wouldn't he have smited someone like me by now, or whatever god does when someone pisses her off?
