Your approach is both rational and respectful - and although I disagree with portions, I appreciate your articulation of your opinion without casting stones.....I agree that we have come so far in trying to portray the fetus as non-human that people have become immune to the concept.  I wonder at the agitation to protect the eggs of piping plovers and not an in-vitro human child (I march for both, btw :-) )

What do you think of the principle of double effect?
