Why are a good portion of photographers always angry or hate everyone Lol

This isnt ment to be a debate im just going off my introduction to this community and i know not everyone is bad :)

Edit: To clear some things up since i didnt really explain well (im very dumb)

- The festival Was public and free and only hired one photographer who i met and was really nice showed me things i didnt know about my camera and pointed me to some spots for some good landscape shots

- The shop i went to was local not some major retailer and i dont plan on ever going back, I talked to some people in local Facebook groups about it and was told that its a common thing to have shop owners/Employees on a ego trip, They pointed me to some awesome shops

- In all this hasnt turned me off of photography this honestly was more funny to me then anything else because ive dealt with these same attitudes when it came to the biking community i just wanted to know if any of yall had the same thing happen or just to joke around about it

So im just getting into photography and people on reddit and the internet have been nothing but nice and mean but with really funny insults that make me chuckle but holy shit photographers out side of the internet are just sad. Recently went to a camera shop to look at some lenses and get batteries and basically was berated for my camera , Yes i shit you not a 50 year old tried saying that its PATHETIC for me to start and i will basically do nothing with it mind you im doing this as a hobby. I didnt even say anything lol i just walked up and waited for my turn

The second one was in a park, Some festival for indigenous people was going on so i though it was the perfect time to get some practice and holy hell it was bad from being elbowed by other photographers to being threatened in broken english (Because of him i really said hmm looks like im getting a new camera) , also had a bottle thrown at me because " I stole someones shot" HOW THE HELL DO YOU STEAL A SHOT LMAO, Luckily i found a small group of others that were really nice and i asked why a good majority of photographers are assholes and got the answer of its just like that. Mind i was not the only one dealing with this ,the group i found told me so many stories of similar things happening so i just want to get peoples ideas of why alot of people in this community are so damn sad and angry
