As to where I stand on the whole 'when does life really start' issue - I have no idea. I'm not convinced, for myself, that it matters. I probably don't value human life as much as I should.

No, I think you're recognizing correctly that the 'when does life really start' question is an unanswerable straw man which serves only to force everyone into one of two diametrically opposed positions (see above re: Simpsons).

If I work up the courage, I will comment more later (when not at work), or maybe to spare Phnee, I will ask them on my own journal.
