While we're restating our positions: I (1) agree that the talking snake is a long, long way from being the best reason for thinking that Christianity-as-traditionally-understood is badly wrong, but (2) think "conditional on sufficiently strong magic" misses the point, because the talking snake is not portrayed as talking on account of any sort of magic.

And I suggest that we leave it there rather than engaging in further rounds of clarification and/or nitpicking.
