I'll be honest here, there are days when I operate under that assumption.
I run into a lot of "photography enthusiasts" as I call them, and they want to fight, argue, gatekeep way more than they seem to like making photographs... and it's not just here, the same thing used to happen in photography clubs back in the 90s. I remember showing one coworker photographs I'd taken, not the originals but the ones in the magazine, the magazine which had purchased them from me, and being told I wasn't a real professional because one had been taken with a 4004 instead of a "pro" camera. I knew, and have met since, lots of people like that and this hobby seems to have its fair share.
I think we all know you can run into the whole gamut, from trendy equipment whores to beginners to experienced folks who just like the hobby and love to help others learn a thing or two. The you tubes adds the inducement of money and the tyranny of the algorithms to the mix, so you might be served an awful lot of the former.
But, my initial point, the problem with crushing stereotypes is that there is so often someone out there to reinforce them. Click on one youtube popular idiot and you're likely to be served up tons of similarly popular idiots every time you return to the you tubes. This is true for photography enthusiasts as it is for everything else google wants you to click on, so it is easy to get jaded.
