This has nothing to do with their reasoning. It's rather based in cognitive development.
Yes, I got that as well. Still, they've concluded (or asserted) that this form of infanticide is morally neutral. That moral framework appears to be taken from what I've stated above. Perhaps I'm wrong.
So you think it is immoral to kill all life?
No, that's not what I wrote. Clearly, sometimes lives are taken to protect others. I agree that it's a difficult line to walk, but at least religionists are willing to walk it.
Including bacteria and mold?
Biblically speaking, that's not life.
And you further assert this is the opinion of all religious people on the planet?
I don't think I've done that. I don't think I've ever done that. I rarely, if ever, claim to speak for anyone but myself. I will, on occassion, try to explain the position of others, but I don't speak for them.
