I quite agree. Airline professionals will HATE to be told this but you are out of step with the rest of the world.
Other industries are more successful in creating a customer-focussed attitude.
It's quite right that you can be honest about the daft things people do but there is a clear line between having a justified laugh at our expense and contempt for your passengers.
It's particularly obvious in the way you treat crew who make mistakes as opposed to passengers.
On a nearby thread you will see 'morons', 'idiots', 'not good breeding material', etc etc to describe passengers.
On the other side of the coin you (quite rightly) take a learning attitude to accidents. The crew aren't 'morons', they were unfortunate that all the holes lined up. They may have made a mistake but it is important to learn from that rather than concentrate on blame.
I think it's great that people like me can real PPrune, and post. But we bring our own perspective.
I doubt if many will agree but so be it.
