I would guess it's a vanishingly small number relative to other reasons for being banned. Don't mention bombs or guns if you're mad, of course. But the habitual obnoxious drunks alone dilute that to virtually nothing, plus the 'flight crew abusers' ("they're just sky-waitresses, so screw them amiright"), and don't forget the 'noble anti-authority protestors' (e.g. any flight crew rules...no, I don't care your views on buckling your seatbelt during take off...I sure don't see it as a civil rights issue). I don't even know how to categorize watching the lady change her infants diaper and stuff the dirty into the seatback pouch...and hour into a 6 hour flight. I've seen so much routine assholery in air travel little could lower my opinion of humanity.
