From my experience I have noticed short men (5' 8" and under) are angrier in life than taller men. Angrier and more defensive with women because they are seemingly not as attractive. Also more needy for other men's approval and with a greater desire to fit in and belong to the alpha male world. I know this is a generalization and I have short friends who don't fit this mold but I have seen it too many times to discount Short Man Syndrome. It's a discussion please don't hate on me.

lol
I do understand what your observing. I've seen my fair share of short guys who are really obnoxious. I guess they feel cheated by nature or something. Don't bash on em too hard though ;). Society has taught everybody to want to change themselves.
