A fetus feels pain earlier than pro-choice would like to believe. Most of us know this but for the crying sake of pro-choicers, look up the literature.
Of course, let us not forget the real concern here, the baby. Pain or no pain, abortion is still killing an innocent baby, it is taking the life of a potential born human being. There is nothing you nor any woman having an abortion can say to change that, or make it right. So just keep in mind, you can rant, you can rave, but you will never win this debate nor argument in the end, because you simply just can't.
Take a look at:
cmdahome.Org/fastmedia/issues_abortion/...
/media/fetalpainwhitep
in all reality, you will find sites that claim pain before 20 weeks and some that claim it not to ever feel pain while in the womb. I stated the bottom line though. Abortion is killing, pain or no pain. It does not change the true meaning of it. So really the yelling and screaming about pain pro-choice, is irrelevant.
