From my cursory run-ins with either community I would say the "snootiness" has very little to do with the fact they train differently and quite a lot with the fact they often train poorly.

Additionally you are creating a ridiculous dichotomy between crossfit and powerlifting. There is such a thing as doing exercises with proper form without necessarily doing 500lbs deadlifts.

That being said I'm sure there are many decent cross-fit gyms where injury and bad form are not a problem - and the exercises they do, particularly the gymnastics aspects are incredibly impressive. Of course you could get those benefits from - you know - doing gymnastics in combination with your workout. And you'd probably be safer off on average.
