>>"If this is true, any restriction on abortion is slavery."

This is currently my personal perspective; I mean not in those words, but yes, today I am that thoroughly pro-choice. This hasn't always been my exact position, I understand it to be extreme, and I am open and even (genuinely!) eager to be persuaded otherwise in the future; but yes - I have yet to see (and it may well exist!) a rational, non-contradictory argument or moral justification to force organ & blood donation before birth, when we don't enforce it after birth.
