Of course women should be allowed to have abortions. Carrying a child has extreme health risks, and complications are quite likely if childbirth is attempted at a young age. "Giving the child away" is possibly an option, but emotionally, it's like delivering a stillborn. You go through the horrible process of pregnancy and the effort of giving birth just to lose the child. While morally, canoodling at a young age is not something I condone, it's okay, and accidents happen, and instead of scarring the 16-, 17-, or 18-year-old girl or young woman with having to bear a child because of one such accident is a thousandfold more unconscionable. The stigma associated with a bulging belly while at school is awful, giving an impression of promiscuity in the youth, and the alternative of not going to school is even more unpleasant; the young woman could lose an entire year of her education!
As for you right-wing, Bible-belt, it's-a-real-child people, wake up: fish have significant brain activity during development, but roe are tasty. We don't kill baby chickens when we eat eggs, since that egg we just ate was never going to be a chicken -- it was going to be eaten, if that makes any sense to you. Embryoes have gills before they have lungs. Killing off fish-baby before it becomes a screaming, kicking, pain in the uterus for the woman that didn't even want to have a child is A-okay by me.
