Hot Corner: Joakim Noah, Kobe Bryant slurs are telling

One question followed Phoenix Suns President and CEO Rick Welts' revelation he was gay: Would a major sports male athlete come out as gay?
Here's the better question: Are major sports male athletes ready for a gay teammate?

Joakim Noah directed an anti-gay slur at a fan during Game 3 of the Eastern Conference Finals last Sunday and teammates defended him Monday. Kobe Bryant said the same slur last month after disagreeing with a referee's call.
Why is sexuality the first thing Noah and Bryant use to attack someone? Both say their remarks came in heat-of-the-moment situations, but would their actions have been different if they had a gay teammate?
I hate to say this, but I'm not sure. They already know anti-gay slurs will get them into trouble and, hopefully, they believe these slurs are bad things. But as long as their reaction to put down another person is an anti-gay slur, it doesn't seem Noah and Bryant are truly ready for a gay teammate.
