>And while it is the crew's (pilot's in fact, I'm pretty sure) responsibility to do everything they must to ensure a safe flight, I believe that people who are afraid of other passengers on the flight ought to be the one(s) asked to take some other flight if it gets to someone being asked to leave the plane. That addresses the fear in the most equitable way possible, and in the safest way possible.
>All passengers are through thorough security by the time they are at the gate. Even if the way someone acts gives me the willies, the idea that they therefore jeopardize my safety is a problem *I* have, not the willies-giving person nor the airline's.
>There is no reasonable logic in removing the person who gives me the creeps from the flight. There is good logic in removing me from the flight if I complain about a person making me nervous.

Tell you what - call it selfishness, if you like, or whatever - but if I'm on my way on holiday, with my family, and a group of weirdos are creeping me out about the flight, and I'm concerned for our safety, it's not gonna be me who volunteers to take another flight; I'm gonna do my darndest to get *them* off!
