You didn't pick up on the fact that that list was entirely a satire, did you?
Or are you indicating that you believe gay people choose to be gay, when the vast majority of scientific research and gay people themselves indicate the reverse is likely? Ever had a crush on someone you didn't want to have a crush on? It's a well known feeling - you don't want to continue devoting so much of your attention to you, but, for a given time anyway, you're nonetheless irresistibly drawn to them even though you know it's bad for you. Would you condemn them for their choice? Because it's exactly the same principle at work here.
