Andrew, I've been posting on this board for eight years now and if you go back and look at some of the replies I've had to my posts you'll soon see what sort of tossers there are out there.
If you want a career in aviation you will need to learn to deal with ***holes occasionally. I've found them in the right hand seat of C150s instructing, to the left hand seat of airliners and everything in between.
Fortunately they are a small minority, but they are definately around.
