I stand corrected - I misread his statement my first pass through the article.
However, I still didn't read more into it than necessary. I just took it as he enjoys either a) football, b) wrestling or c) kickboxing, and if he can't do any of them, he's cranky. He's competitive, and his chosen sports involve physical dominance (being an avid MMA fan and jiu jitsu student I really don't see the big deal here). As far as how he worded his statement, if you've ever worked around extremely intelligent people like him who do physics, math, etc. (I currently manage a network for these types of folks), you hear things worded in ways much differently than what you hear in a social setting with, we'll call them.. 'people with social skills'.
I just don't understand some people's reaction to his statements.
