Being a member of a number of online forums ranging from religion to swimming pools to aviation and electronics, the thing that jumps out at me most is trumpet players are overtly opinionated and are far more verbose than the average individual.
Perhaps this is a prerequisite for becoming a trumpet player in the first place. The only other group of people that are this opinionated are airline pilots. In some cases, you could substitute the term "hard headed" for opinionated. Maybe these activities require more of a type "A" personality.
It is always interesting to note that when a question is posed here there is rarely a consensus in opinion. "What kind of trumpet should I buy for my beginning student to play"...and there will be many responses with widely varied answers as to the direction to go. In a similar instance I counted as many as twenty different answers from about as many responses, which would make it a bit challenging to come up with a good answer for the individual.
And when things have a "wheels off" direction, the site moderators employ their collective wisdom to get the train back on the tracks.
We are all entitled to an opinion, and being unique individuals, the opinions likely will vary widely. Makes life interesting, right?
