God, I hope they don't feel pain. I'm pretty sure the near term baby does which you conviently ignore as well you ignore how nerves can deliver impulses representing sound and the same nerves are not able to deliver pain. Further, if the baby is unconcious all those Mom's that talk to their unborn babes must be nutcases. At some point the unborn feels pain, and thats a point at which I would not consider myself knowledgeable enough to know and my guess is you are not either.
Even if the DR is wrong what is wrong with assuming they feel pain and administer pain killers just in case ?
If as a matter of faith you believe your God approves of abortion and will not suffer unborn children to feel pain, then your conscience is clear despite the dumptruck loads of mangled limbs, viscera, and brain matter removed from abortion clinics across this country every day. If that is a matter of faith, you will not put your God to the test by giving the targeted child an anesthetic. Tha would be a double-minded denial of faith.
The god that some abortion supporters worship is a convenient god indeed, commanding them to behave in manner most congruent with their most selfish drives, mercifully striking them blind and deaf to the vision and cries of terror of the innocent.
