I agree, that's probably a faked picture....however..If the baby DID look like that would it effect your opinion about abortion? (I think I already know what your answer will be) If not, is the baby any less of a human because it's not fully formed and anatomically correct?
That photo may indeed be fake, but give that baby a couple more months and it WOULD start looking like that (yet bigger)....and people abort 3-4 month old babys all the time.
