I don't disagree with the OP or anyone else when it comes to arrogant behavior. I just don't run into it much among climbers, although it certainly stands out when I do, so I'm not sure why it is such a big issue here.
On the other hand the topic must interest me enough to take part in the conversation.
And I will freely admit that having breakfast buffet at Curry after climbing El Cap, the fat tourists did not impress me...
One afternoon I was hanging out in El Cap meadow. Some Dad with his family was within earshot, and he pronounced to them "You know, those climbers are really just a bunch of dirtballs, but you still have to admire what they do..." I thought he about nailed it.
So, welcome to SP and congrats on your choice to head for the peaks...
