When I sit in the same cabin, and I'm buckled up, the previous poster (or his body parts) will be bouncing all over the seats of the same cabin, which is a danger to me. So I still prefer that he also buckles up.
As do I, but he's a poster on HN and not on a flight with me, and I have considerations for the value of my time and the integrity of my sanity when dealing with people who think that "intentionally obtuse" is a position in argument.
