In reply to Rigid Raider:
I've noticed this too. I think there's a kind of camaraderie among people with dangerous hobbies. When I started riding a motorbike for example, I noticed that all bikers nod to each other as they go past.
Agree that the climbing counterculture is good though, and I like the general principle of 'let's be mates unless there's a reason otherwise'. The only problem is when you get so used to being around climbers that it becomes the new normal, and then when you return to humanity, with miserable, aggressive and unnecessarily unkind people, it seems all the worse!
