If someone is indeed wrong, why is it a bad thing to tell him that?

The difference between he and I, though, is that I've invested thousands
of dollars and countless hours learning the art and science of aviation,
proving myself to instructors and examiners, and earning the experience
in my logbook.

No matter what a person has invested, that does not guarantee that he is
right, and he must still be willing to accept it when he is wrong.

For me, aviation is a discussion, not a struggle amongst egos.
