> Equal protection under the law would be my first pick for constitutional protection of abortion. There are very few life threatening things that the law compels men to do. Yet the law can compel a women to carry a fetus to term against her will?

I don't think it's the court's job to equal the playing field on biology.

But since you put it like that, wouldn't that mean the father also has the right to decide for or against the abortion of his child?
