Only a heterosexual person, who never had to worry about a co-worker's, schoolmate's, a friend's, or their own mother's or father's reaction when they told them who they wanted to go on a date with, or who they wanted to hold hands with, would be able to say something like this.
And to reduce it to "what gets inserted where" is a pretty shallow understanding of sexuality. I'd like to think my relationship with my wife is a lot more than just that.
I think that's the irony of this issue....A gay person can say how they feel, give all the reasons they believe they are the way they are, and it's acceptable....a straight person can defend gay people, same thing...but if a person is not sympathetic or in agreement with anything dealing with this issue, and they are shallow, right-winged, Bible thumper, narrow minded, or whatever else.
You are correct, your relationship with your wife is more than just about the act of sex...and a gay person should feel free to love who they want....and I don't look at your relationship with your wife as courageous, or anything that should be put on a pedestal, just like gay people in love shouldn't be either. Who people love shouldn't matter to the next person....but with this issue, and the sympathetic nature that has come from it, like Fewmit said, a changing view on homosexuality, the media and others are now esteeming them for declaring this aspect of their lives.
We can get into the a big debate of all the pro's and con's if you like...but when it comes to Professional Sports, the Military, and other fields, this "courageous" decision has far reaching implications that affect more than just the person coming out....and not all of those things are positive for everyone involved.
I am not saying that a gay person shouldn't come out, or shouldn't be able to be honest with who they are, but just like in this post, where I point out a different point of view, and am called shallow...there are others that have to work in close proximity with that person, who might be very uncomfortable it (their feelings are real too, and it doesn't make them a bad person)...whether its a trust issue on the basketball court, in the battlefield...or a new-found awkwardness taking a shower around that person...others are affected. But if any of those people are genuinely uncomfortable about it, their feelings don't matter, because we are "evolving" as a nation, and their teammate made a "courageous" decision.
