I tend to agree, though given how little information there is about the man’s behavior it is hard to judge.
Unless the man was truly disruptive, I think throwing him off the plane for sexist comments would only serve to reinforce the stereotype, some might have, that women are too “sensitive” or “emotional” to be airline pilots. Ignoring the jerk and flying the plane flawlessly would show a lot more from the pilot than kicking the guy off the plane.
Of course, if he was causing a real disruption, as opposed to merely hurting the pilot’s feelings, she did the right thing.
I wouldn't want some chick with hurt feelings anywhere near the controls of an aircraft. If tossing him out made her feel all warm and cuddly, I'm all for it. < /ducking >
