Well I wouldn't say "no boarding for you", but I was breast fed so boobies don't scare me (OK some do, but they're the very rare exception).

That being said, no one would want me as GA/CC as "behavioral problems" would be handled in a Procrustean way - with a double helping of "severe." Carry-on too big or you've got too many bags - they get checked; no arguments. You aren't in your assigned seat, you're told (not asked, told) to move. You're using a cell phone or other device; it get's turned off NOW. etc. etc. etc. Any args and your *ss is off the plane.

Hmmm, wonder if the airlines could install a "holding cell" or, more accurately, a brig in the cargo area (assuming someway of accessing that area). A nice quiet place to "ensconce" less than properly behaving pax. Nothing too comfortable (or everyone would want one). A hard seat (with restraints), a metal toilet and, most certainly, no AVOD.
