GP is the one who argued “not 100% safe” as evidence of inherently unsafe.

I agree with you that it’s a comically wrong threshold, which is why I offered that series that was progressively more safe but never 100% safe as examples against that line of reasoning.

Make the threshold "won't kill you 99.9% of the time, even if you have little to no training at that specific activity" then. Is that specific enough for you to engage meaningfully with the conversation at hand, and show why you think driving is at the same side of this threshold as eating grapes or using crayons?
