Confused how one can come to that conclusion. If violence is not a trait in a modern society, how big people are should be of no consequence. Back in times of the caveman this was an extremely important trait because violence was an aspect of daily life that had real utility. Now, people can go their entire lives never having been in a fight.

In fact I would argue having an arms race for ever bigger humans is antisocial and detrimental... just the carbon footprint aspects alone is a good reason to discourage that. The extra stress on our food system. Bigger cars, airplanes, fuel, etc... as opposed to women dig it and you can beat people up. Really?
