Oh Dear Lord...he's a "GUY"

So, despite my best efforts my son has turned into a "guy" at least when it comes to sports..
I'm not sure how it happened...but I'm appalled.
I walked into the living room the other day only to discovered my darlingangel....Watching football, and I dont mean the exalted sport of soccer.
I mean American football...the possibly most pointless sport in the history of pointless sports.
How did this happen? I dont watch football, and his father is too uninvolved to have any sort of effect on him..so clearly I am troubled as to where this proclivity for one of the most boring spectator sports on earth has come from
Has some stranger been showing him football footage? discussing sports with him?
Is it perhaps that being a sports fanatic is indeed something you're born with? A latent gene
Like balance? or the ability to accessorize?
Which would make sense since my verybestfriend H (and darlingangels godfather) told me he realized he was gay when he was about 8 or 9. (as you see I fall firmly on the genetics -v- choice side of the lawn with this issue)
How on earth did this happen? Have I not directed him toward the arts? books? music? Soccer AND Hockey are both religions in our home...so why would he break his poor mothers heart and become a FOOTBALL FAN???
Granted I still refuse to buy him a playstation/XBox/gamecube But surely THAT could not have retarded his intellectual/emotional growth this much, as to make him a football fan...I am absolutely at a loss here.
Do they have interventions for this sort of thing? And would it/could it be effective on a 3rd grader?
