AofA there are even a few of us who were/are aircrew who didn't/don't chuck biccies or tip coffee over pax either.
My aviation background is pretty diverse. Just because these days my feet don't leave the ground in a tin can to earn my wage, doesn't mean I'm any less interested in aviation or pprune.
As much as it galls you, those people who are not 'aircrew' still have opinions and questions, and not all of them are out to wind you up.
A very long time ago Lord Fyne recognised the deep interest in things with wings from non aviate types.
Perhaps you may to.
