I hate Kobe and all, but this is not a big deal. OK, he got caught on camera saying it, so fine him.
I'm sure KG throws worse around dozens of time per game. The baseline (especially immediately after exiting from gameplay) is still the game.
I'm guilty of using insensitive language (when I am around friends). Does that make me a bad person? I'd like to think not, but I am not a superstar athlete, nor am I a role model. Granted I don't use that type of language at my workplace, but I'm not nearly as passionate about my job as an elite NBA player.
