Hmm.. I was listening to Rome today and he said something that didn't make sense to me: "He came out to live his life... you can live your life, why can't he live his?". You can't blame that on a cruel world -- millions of people haven't, but gays can?
I will admit -- society can make a person uncomfortable, but ultimately, you can't let people control your actions like that and then you think you deserve some sort of welcoming party when you decide to take control of your life again. Why couldn't Collins live his life? Because HE didn't want to yet.
Really, as a black man in America, if I let racists whites keep me from moving into a certain area, marry a white woman, work in white corporate America, can I get an audience for "taking control" of my life and getting that good job, marrying that woman, moving into that white neighborhood? While many may applaud my bravery, those people who are honest with me and themselves will say that they're glad I finally did something I should have done a long time ago -- taking control of my life and to keep it moving... what I did was nothing special, and defintely not worth attention-whoring Sports Illustrated over.
I think you underestimate the power of social pressure. People are social creatures, and the prospect of being shunned is an incredibly powerful force. I'd love to claim that I live my life entirely free of judgmental influence of others, but it's simply not true. If there was a part of me that, if revealed, might cost me my career, my family, and my friends, I'd probably want to keep it secret as long as I could.
The example you give, of being a black man encountering racism, is a worthwhile case study. You don't feel courageous living your life freely in part because the vast majority of society is with you. 60 years ago, that was not the case and it took a lot more courage (and entailed far more risk) to do what you do now. Were black people then morally inferior to black people now? I certainly don't think so.
There's another big difference between being black and being gay: you have a long, long family history of knowing what it's like to be black. You can ask your father and/or mother what to do when confronted with racism, you have a culture and traditions built to respond to racism and act as a bulwark against it. Gay people don't have this. Their parents are most likely straight. Until recently, they grew up without gay role models. Many of them felt that who they were was
wrong and that they must suppress it. It's difficult to tell someone to just be who they are when they have no model for what that should be.*
Just as public support has shifted on racism, though, so too it is shifting on being gay. Even 20 years ago, coming out could have been a career killer. Saying you're gay then would have been truly heroic. At this point, you're barely getting to half that don't think being gay is a sin. Depending on where you live, though, coming out still means risking being disowned by your family and shunned by your community. In another 20 years, I hope that it will be trivial for a notable athlete to thank his husband for his support while receiving the Lombardi trophy or being inducted into the Hall of Fame. For now, though, we have to content ourselves with a journeyman at the end of his career setting an example for younger players of who they can become.
*I should note here, however, that the heritability of being black cuts both ways. The centuries of abuse have created a cultural scarring that will continue to last generations, something gay people are far less likely to have to deal with.
