I want to be perfectly about my response above.
I don't think that climbers should ignore and not use improving techniquest and equipment for safety.
I'm opposed to the snotty attitude of the original poster.
It also should be said that teaching kids to hip-belay as a back up isn't inherently unsafe. During an incident with a gri gri at smiff that I happened at smiff when I was climbing with a group of friends, a hip belay was employed to protect the climber until we could switch the gri gri with an ATC. Glad that a few of us had been taught the hip belay.
as for climbing in street shoes...it may not be the best for the rock but its not inherently unsafe.
Don't take a holier than thou attitude and then be surprised when people don't rush to your side.
