What would becoming more mainstream accomplish?
Not that it will ever happen, but how would it change things for you?
Becoming more mainstream would bring more money into the sport. One of the biggest tragedies of competitive bodybuilding is that there's no money in it. Also by becoming more mainstream that would bring in more competitors, and a respect for bodybuilders and the whole bodybuilding endeavor.
I will agree this video is some funny, and it really is not 'a giant step' backwards. But still, when attached to bodybuilding a lot of the mainstream public would look at this and think what a weirdo.
