While it is unfortunate that some people are of a larger stature, that's how it is sometimes. Some people become that way through their lifestyle, others have conditions that are out of their hands. I would not like to be the gentleman that cannot safely occupy 1 seat, but I also would not like to have half a seat for myself. Each passenger pays for 1 seat. One entire seat. If I take up even 51% of 2 seats, I should purchase both of those seats, as the pax next to me is only getting 49% of the pair, while he/she paid for 50%. If I want to build an additon on my house, I cannot just build onto my neighbors property. I must keep it in my own, or purchase the land I require. It's the exact same with seats in a plane. Unfortunately, the lowest unit of airline seat is ONE seat, so if you only "spill over" just a little, you must purchase an entire extra seat.

Aside from the comfort factor there is the safety factor. I've never had to evacuate an aircraft, and I hope I never do. Should that ever happen, I don't want to be stuck behind a fellow passenger that cannot get out of his/her seat quickly enough to facilitate my evactuation. That may come off harsh, but that's the case. Very similar situation with security issues. I'd rather have my feelings hurt, and other passengers have their feelings hurt by security procedures, than see another terrorist attack, or, God forbid, be a victim of one.

Again, I do feel for people that cannot control their size. If airlines choose to make their seats larger to accomodate larger pax, that is their choice. The current seats accomodate the vast majority of our population w/ no issues. Airlines continue to reseat passengers at no charge should there be an open seat on a flight, sometimes at the expense of nonrevs. I cannot be reseated just because I want the extra space. No matter how full the flight, if a passenger occupies more than one seat, they should purchase more than one seat.

Again, I apologize if this comes off harsh...
