You're welcome. That's perfectly fair.

FWIW, I wasn't trying to say that the position should be "supernatural by default" - just that there's a lot more to account for in NDEs than what you've described, and that I don't know of anyone who's looked into them seriously who holds to Blackmore's attempt at a purely materialist explanation (another way it falls down - if oxygen starvation accounts for NDEs, they shouldn't happen for people who aren't oxygen-starved, but they do).

As an agnostic who really wants to believe in the supernatural but has the same gut instinct that there needs to be evidence for it, I have a plausible materialist explanation for NDEs, but it's rather more involved and isn't especially rigorous.
