NBA wrong

So is the NBA way off here. I understand gay people have every right to play sports and live and do what ever they want. Come on now really, if you are attracted to the same sex should it be promoted by a sport league to use the same locker room. Their is no way in hell anyone would let a guy in a girls locker room even if he admitted he was gay. So why is it OK for someone that has come "out" to use the same locker room.
