"I would hope I am a cut above a CFI."
What's that supposed to mean?
I'm a UPS 757/767 Capt and a CFI since 1980. In many ways, the CFI part is more rewarding than then major job.
A professional pilot is one who is getting paid to perform a service. CFI's are in that catagory.
Now, if your point is that a CFI, who has never stepped foot in an RJ or worked at a 121 airline, should be overly negative towards those who work for Mesa, then I'd agree they don't have much background to stand on. But you need to watch how you put things.
