Whether the fetus is a living organism is not in question. It's whether or not it is a living soul. And, as I have been trying to point out, there are Bible grounds for believing it is not.
And as you point out, there are Bible grounds for respecting the fetus, whether it is a living soul yet or not.
But I am arguing that the "life of the unborn" and "killing innocent babies" and "abortion is murder" arguments (and justifications for seizing political power and controlling others) are based on "life begins at conception" -- the ensoulment of the fetus -- ideas, which the Bible does not support.
