My experience may be a bit dated (late '00s), but from the few times I tried climbing (and from interacting with the climbing-friends of people I knew from other activities), I found most of them to be standoffish, and a little bit too "proud" of their chosen hobby, as if climbing was somehow a noble endeavor, and that participating in it showed that you were of good breeding or something.

I certainly have no basis in painting all climbers with this brush, but this was my experience, and I found it to be pretty bizarre. Completely turned me off to making climbing a hobby of my own.
