Simply put, the act of murdering a helpless little baby. Pro-choice activists feel that whether or not a woman should carry a child to full term should be her choice, but what they seem to forget is that the woman made her choice. She chose to have sex. Every person knows the risk you take when you have sex. Even a young child can understand that. That risk especially increases when you have sex without protection. So tell me, where exactly is it that a woman isn't getting her right to choose? If she isn't ready to deal with the consequences, then she isn't ready for sex. It is not fair for the child to be punished because the mother screwed up.
Now people are going to argue with me, "but what about in the cases of rape and incest?" Let's look at that, shall we? Honestly, how many of the abortions carried out are actually for that reason? Probably less than 1%. Women use it as their form of birth control. Often times, they have more than one. I honestly don't see how anyone can live with themselves after murdering a baby. If you don't want the child, there are plenty of loving and responsible people that do. Have the baby and give it up for adoption. There is no shame in better a couple's life, as well as a baby.
I was irresponsible when I had sex and got pregnant. I don't want it so I will end its life by having an abortion.
