On the other hand...
Many microlight pilots think they're looked down on by other (Group A) pilots, and perhaps they are. They retaliate by saying they're better pilots, and have more fun, and that their clubs are more sociable. Some helicopter pilots (not me, honest!!!!!) think rotary is the only way to go, and the converse...now, no eggbeater jokes please. Twin pilots look down on single engine pilots, taildragger pilots make derogatory remarks about spamcans. Meanwhile, we few TAPs (total aviation people) fly anything we can get hold of (even kites) and wonder what this is all about.
Elitism in GA? Yes, definitely. But not quite the way you meant it I think, cinman.
