Let me answer your question by asking you one:
If I pointed you to a scholarly article on NARAL's site or Planned Parenthood's site, would you take it at face value and ignore the source?
Pictures speak louder than words. If I sent you to a website where Doctors or whatever had written an article, it would be different but go to a website where there are actually pictures of aborted babies. You will be shocked.
Are you denying that abortion happens as stated? If so how is it done? Especially partail birth abortion?
