While identifying yourself with your Deadlift alone is not a good thing (there's more to life than that), insulting people who have big deadlifts is ignorant.
I suck at long distance running so marathon runners are stupid. Let's see them beat me at golf or bowling; those are skills that involve multiple muscle groups and the right combination of power and accuracy. Running is easy.
The fact that someone is good at something less "skillful" than another feat doesn't negate their accomplishment.
World's Strongest Man competition is stupid and irrelevant because anyone can pick up a rock and put it on a pedestal. That's not impressive at all.
And if you haven't read all of these posts, please scroll up and and look at the videos and pics of some of this forum's 600lb deadlifters. They look like they're plenty capable of other things....probably even snatches.
