You guys are arguing over semantics.
QSK is quite correct to regard someone who works in the aviation industry as an "aviation professional". Their profession is in aviation. In this way a flight attendant is an "aviation professional". This does not necassarily mean that a flight attendant would be the best person to work on airspace reform however.
DirtyPierre is using a more restrictive form of the term "aviation professional" which is probably limited to senior commercial pilots and ATC personel.
