Until we discover something that can prevent pregnancy 100%(other than abstinence of course) we all have to take responsibility for our actions. The only thing pro-choicers defend is the right to not take any responsibility for a innocent life and the parent's actions. Abortion only reinforces the care free mind set about sex; with the help of abortion you can now have as much sex as you want without worrying about having a baby because you will be killing them off as you go.
