Don't know how well it applies to this incident, but, the combination of testosterone and pride is highly corrosive and volatile.
A lot of really talented kids have been told from an early age that they're the best thing since sliced bread, then they're told they need to be more aggressive over and over again, until it's a habit. So, combine a bit of arrogance with a motor that's usually in the "on" position for elite athletes and add a dose of youthful lack of judgement and you get stupidity.
Accounts for a lot of things, not just aggressive behavior, but just assumptions of "right-hood". No, you are not always right, you are not always going to win, and your chances of often being right and often winning probably increase once you learn it. Or as an old friend used to quote, "know when to hold em and know when to fold em".
There's a strong element of learned violent behavior...not just among athletes...that needs to be unlearned...the fact that he couldn't distinguish between a man and a woman in his response indicates just how far the pendulum has swung...
A fight between two guys probably wouldn't raise any eyebrows...hitting a girl in Texas ain't gonna fly...
Not sure if this is the case but more often than not it comes down to parenting. That or a lack of it. ...Manners and discipline start at home, or should.
