Abortion is in and of itself "monstrous." And the "right to choose" is not in the constitution any way. The so-called "right of privacy" is what was "at stake" in Roe v. Wade. Yes, "abortion is a crucial choice" as you say. It gets to the "crux" or center of issue of morality in this nation and around the world. It is based on the concept of actions not having consequences.
