I agree it is wrong to belittle a Piper - the fundamental principles of flight remain the same for larger aircraft.
I hope Tima84 isn't one of those who'd been persuaded by parents or family to take up a flying career. Or perhaps he had rushed through his initial IR and ATPLs without really understanding them. I see a lot of students in these situations and their nerves show when they go for a checkride.
Those who really have a natural flair for flying tend to really want to do it themselves, to the extent they may have learnt and known everything about flying a Boeing or Airbus before they even start their type rating. And some of them are much younger his age (26).
It's the same with other careers like medicine or law.
