Having an opinion and sticking it where it doesn't belong are two different things. I am convinced that Justice Scalia restricts himself to applying the law. In this case, I believe as a justice he would defer the question of abortion to the states, based on constitutional law, not based on whatever his personal opinion on abortion is.
If you want to say that a person with enough integrity and ethics to do his job responsibly is a rarity, you can say that. I have no data on the subject. I maintain that ethical jurists with integrity are what's needed. Not pro-life activists.
To be anything but a 'pro-life activist' is to deny every principle this country is founded upon.
Those who will betray innocent babes in the womb, on or off the bench, will betray any principle.
Your neat little world that somehow presumes disinterest by some imaginary individual on this issue of life and death just doesn't exist.
