The purpose of contraception is to prevent a pregnancy. Other purposes of contraceptives include battling various learning disabilities, combatting depression, and assisting in the fight against anorexia in a rare case. On the other hand, the purpose of abortion is to save a mother from irreparable harm, not simply prevent pregnancy or childbirth. I don't think abortion should be used as a method of getting rid of a child simply because one doesn't want a child, but I'm also not one who thinks it is my right to make that choice for someone or, more importantly, let the law decide what is irreparable harm and what isn't when a medical professional should be making that call alongside the to-be mother. I don't think politicians should be able to do make any judgment other than a general one when it comes to medical procedures, and saying abortion isn't okay under any circumstances (or even under certain circumstances like rape/incest) are not general enough to make abortion both regulable and accessible when necessary.
I don't know why pro-choice is considered anti-life, or why pro-life is considered pro-life. Pro-life consists often of people who are far and away destroying the lives of millions in this country (and others around the world) through other political choices, yet they have the advantage of connotation. I don't get that.
@KC ... as for "feeling good and having fun is sinful," there's a reason circumcision exists. There's a reason that men, boys, women, and girls are genitally mutilated in many places around the world, including any that allows circumcision as we do. It is a medical operation, often not performed by a medical professional, on a young child incapable of making his own decision on a matter that doesn't threaten his safety at all. It's not simply religious tradition, it's religious tradition for the purpose of upholding religious politics, which have for many centuries declared sex to be bad when done outside of marriage and not for the sole purpose of procreation.
