Looks like PPRune would be a good place where you will get reasonable answers.

On a serious note, have you put yourself in his position? Maybe he does not have any reference as how contract and expat flying works and asking legitimate questions. Rather than typing that long response in his mockery, you would have done a very good job if you had provided some thoughtful opinions drawing on your aviation experience.

I am no expert by any means but I help with whatever information I can. You surely did not fly the big irons right out of school and were in his position many moons ago with a lot of questions, uncertainties and enthusiasm- so why this mockery?

If you aint got nothing nice to say, say nothing!
