>>925387>>925395>>925396The type of brash, obnoxious behavior you are describing has nothing to do with where a person goes climbing most often. It is endemic to privileged youth in cultures that primarily value status/social currencies and deride or simply fail to teach humility.
If you want people to act differently, you're going to have to do something about it yourself. And the best place to do that is at a climbing gym, where you can talk to the most new climbers.
