I am anti-choice if the choice in question is whether one should be able to become the live-in romantic partner of the then-40 year old obstetrician who delivered you. Call me intolerant if you want, but I strongly believe that your romantic partner's name should never appear on your birth certificate. Then again, I know some would say that they wouldn't want santorum on a marriage certificate, but I think that that is a personal choice between two consenting adults (as long as the one guy wasn't the other guy's mother's obstetrician (see above)).
