I think it really depends on the local scene. I've been part of very toxic boxing gyms, BJJ schools, but also others where everyone was respectful.That, to my mind, is the value of the MMA approach, though I freely admit that I don't feel at home in the MMA culture.
Some MMA places are absolutely terrible, usually because they are run by horrible human beings, and those places attract a certain kind of person.
Others, like you mentioned, are full of cool people, who also tend to flock together.
My favorites are still the wrestling people, male and female. That's a really tough crowd, and sure some of them have issues, but there is always a great sports unity going on there. The jackasses in the group tend to isolate themselves.
Sure the whole "jock" stereotype is always mentioned, but it's usually not fair,these are just people who follow the advice of champions and train harder than most. And MMA fighters tend to train way harder than anyone else in martial arts. I know hard as nails Judoka and Samboists who would never step in a cage, not because they are scared, they just know they don't train that level.
