The pro-life position is the product of a false and lying sentimentality, encouraged by the false and lying desert religions. It is an abomination.
The only religious basis I have for being pro life is the sanctity of life in the eyes of God. I proceed from that. And I think any reasonable secular moral framework also considers life to be, if not "sacred" per se, then at least of paramount value. So I doubt the end result would be any different from a secular approach. The real issue is what construes life and what does not.
But by all means, do not let this get in the way of your profound diatribe against the "desert religions". By all means, keep on using that phrase. I can tell you're quite satisfied with having thought of it.
