I couldn't agree more. I personally think Dungy is an idiot for those comments. First of all, who cares if it causes a "media distraction" it will pass. That's the price you pay for progressing with human/civil rights, just like you mentioned with the color barrier broken in baseball decades ago...
Rather than commenting on it being a media distraction because the guy's gay, why not go after the media for making such a big deal about it? That would be the smarter move, but he won't do that because he doesn't want to bite the hand that feeds him, even if it is the truth. Besides, it hasn't even become a big deal as of yet anyway. The biggest deal so far is Dungy's comments themselves, so he is only adding to it with his ignorant statement.
Really, it doesn't make a lick of difference if the guy is gay or not. It's not like he's gonna play grab ass in the locker room. Gay or not, he will maintain the same professionalism as any other athlete. Besides, they already do borderline gay stuff in sports as it is like patting each other on the asses sometimes. I suppose they will get offended if a gay guy does it to another player right? Because he's gay so he's GOTTA be flirting rather than doing it for sportsmanship like everyone else right? Gimme a break...
Really, what it boils down to is pandering to religious groups and conservatives. And let's be honest, if they had it their way, the world would never progress. It would regress and devolve really.
