I've got a 13 month old daughter trying to grab the mouse from me, so I'll give you the POV of this father.
Abortion is not murder, as long as it is performed before the child is unable to survive on it's own or without intensive medical support - I don't think anyone can justify abortion as 'taking a life' when said life is incapable of living.
After this time, I think it's up for debate and as a father, I'm proud of my daughter and couldn't wish for anything else - even though my social life has taken a nosedive. Personally, I don't agree with abortion because of what I have, but I appreciate other people will not want it. Why would you carry around something you don't want for 9 months?
Sure, giving the child up for adoption at birth is a possibility, but I don't think it is fair to force women to carry a child to term if they can't stand the idea of being a mother or if they don't want stretch marks, or feeling sick, bloated, lethargic... heck, my fiancee went through 62 hours of labour. If you don't want the child, why go through 62 hours of labour? Then there's the classic of getting pregnant through rape. Who wants a rapist baby?
I still think 'murder' is a very pretentious term for abortion used more for attention-mongering than anything else, regardless of the true definition devoid of emotive implication.
In the same light, a woman who falls whilst pregnant and suffers from a miscarriage is guilty of 'manslaughter'. Still an offense worthy of a jail sentence.
