Sure, in this case, such a person is probably ignorant, because the facts say that flying is an unusually safe means of transport. But you don't need to have flown to know that. The facts are the facts, whether you've flown or not.

Never say never, but usually advice from the ignorant is not worth much.

I've found that non-flyers know very little about airplanes, but I agree that facts are facts.

As far as I know, nobody has ever even tried to jump Grand Canyon on a motorcycle. But they tell me riding a motorcycle is not at all dangerous. Falling off, and running into things certainly is. However, I am not very well quaified to talk about that since I never ride motorcycles. Never have, unless you count that really small one I had in high school. It was slower than a modern bicycle.
