Why are short guys always over compenstating?

Everything you listed has zero to do with ones height let alone compensating for anything.

1) Bodybuilding is a sport that has participation from both short and tall men and women for that matter

2) Share your stats on that.

3) Why only pick-ups. Why not SUVs? Women love those maybe they're making up for something as well?

I'm a tripod

Then there are men like Robert Reich, who are brilliant and have nothing to prove. Perhaps if some people didn’t mock and discount the "vertically challenged" (which is ridiculous, when you think about it) some wouldn’t feel a need to overcompensate.

Little man syndrome, most actors are short little fellows too
