Sure there have been a lot of gay women athletes, the most recent to come out being the best woman player of this era, Britney Griner ex of Baylor and now with the Phoenix Mercury. Men that have come out have been few, retired, and none active.
Sports Illustrated breaks with the story that Jason Collins, an 11 year journeyman centre in the NBA has come out. "I'm a 34-year-old NBA center. I'm black. And I'm gay." Tina Fey would call him a two-fer. "I didn't set out to be the first openly gay athlete playing in a major American team sport. But since I am, I'm happy to start the conversation. I wish I wasn't the kid in the classroom raising his hand and saying, 'I'm different.' If I had my way, someone else would have already done this. Nobody has, which is why I'm raising my hand."
