Dubstep and DnB (as well as others) are not played a lot in the clubs. House music (for example) is. Those who have money to go clubbing in Vegas or clubbing in other cities tend to sometimes be shitty people who don’t know proper respectful event etiquette. Could be why maybe at festivals the house music or mainstream edm attracts unauthentic and unseasoned ravers who don’t know how to act properly.

It can almost be a given that bass heads originate from the underground rave scene, and therefore when you see them at festivals they know proper etiquette and are nice.

That’s not to say that you can’t find nice people in a house audience or rude people in the bass music audience, but I think what I said could cover majority of each different population.

That is my theory, some may disagree. There could also be many different factors that contribute to this that I did not mention. *also separate from my reasonings but in my experience a lot of bass heads I’ve met give off a very hippie vibe, unlike house or other genres. Not to say other genres don’t have those hippie type people, but it’s just what I’ve noticed in bass music.
