So whatever most children grow up with is beyond questioning and acceptable?
Its an extreme sport and like other extreme sports has risks.
Your intellectual arrogance is absurd.
Do you even read what you type? Or for that matter, do you even read what others type before typing a response?

Of course its not beyond questioning. But the fact of the matter is that children who grow up playing those sports tend to watch those sports when they get older. Bodybuilding is that "rare" sport that most people don't watch unless they have directly engaged in it at some point in their life. To like bodybuilding, and to have never touched a weight in your life is BEYOND STRANGE. Its culturally-based. Bodybuilding is an esoteric sport and tends to draw people who are actively engaged in the sport (either through recreational lifting or competing).
You try to come up with these intellectual arguments to sound smart, so you do not fit in with the stereotypical meathead persona. Sorry, but you're a meathead. Stick to the weight. That is what you're good at.
