It’s the same with Guitarists too.
Oh you play through a solid state amp? There’s no way you can get a decent tone out of your stock humbuckers. Shredders aren’t musicians, Jazz is the only path to being a ‘true guitarist’. PRS? Bedroom guitarist. The list is endless.
It can be found in all walks of life where there is a group of people. I’m looking at you, spliff politics.
My personal opinion? The thought of petty bitching simply doesn’t occur to those who are happy.
