I'm just PAX, private pilot and airplane lover.
That said, I'm glad I seem to live in a different universe than these thugs and those of you that have to haul them. I fly a few times a year, mostly up and down the pacific coast of the US. I've never seen any of the flight crew abused by PAX. I have seen spontaneous applause for a nice landing through a bumpy approach, a "nicely done" to the pilot by the passengers on the way out, and lots of patience and politeness to the cabin crew.
Now TSA is a different matter....
