I posted this as a comment on an anti-gay, pro-religion blog, the Blog for Life, Marriage, & Religious Liberty. Since it seems unlikely that they'll actually publish it, I thought I'd publish it here.
In the 1950s and 1960s in small town USA, we weren't all that aware of gay-ness as an issue. Betty and Pat ran the airport together, and everyone respected them and treated them well. In 1979, my boyfriend was in a car crash which left him partly paralyzed. An employee at the rehab hospital rented rooms to those of us with relatives in rehab. My housemate wasn't as lucky as I--his girlfriend was in a wreck which left her brain damaged. My boyfriend could say, "I want my girlfriend here." She couldn't say that about him. When her parents visited, he was excluded. That's when I learned what it was like for anyone who isn't married. Later that summer, my boyfriend and I married, and when he went into the hospital, it made a huge difference in the way I was treated. Only those who are married have the right to a real say in their loved one's treatment. That's when I became an advocate for gay marriage. I was able to make it easier for my boyfriend and me; my housemate, however, had no say in his girlfriend's treatment, and since she was mentally disabled, he couldn't just marry her. That's when I realized how unfair and horrible it would be to be gay and unable to marry. That's why I believe that the right to marry is critically important for gays, and I can't figure out any reason why they should not be accorded that right
