Seriously?

I feel like this would offend not only trumpet players but also French horn players

I have freinds who play those instruments, and we're all in band ( I play alto sax, so horn and us have similar parts) and we were all offended by this. So was my band director.

Not only is that not a trumpet, he’s holding it completely wrong. I play Bari sax and this still triggers me

my dad is a band director and he saw a picture in a magazine of a saxaphone player posing at a fountain, and he said "i know for a fact that isnt a saxaphone player... his right hand is on top instead of his left and he is posing"

I play percussion and it triggers me

Bro, my band got a French horn donated today

I play trumpet and I have been summoned to say THATS A FRENCH HORN NOT AT TRUMPET ILL SHOW YOU A TRUMPET that is all.
