I agree, and I'm very disappointed that the gay community chose the "marriage" route. They could have fought for all people, straight and gay, to have the right to define the terms of their relationship, by expanding the status of civil unions. But instead they just got on the "marriage" bandwagon, and defended traditionalism. They only thought of themselves, not their opportunity to contribute to more freedom and dignity for all.
I'm generally happy for gay marriage; in fact my sister is gay and married, and has a daughter, and our whole family has been very happy with it, and we visit each other all the time. But I just think it's anti-climatic, compared to how much greater the progress would have been, if we'd gotten the government out of the business of defining marriage entirely.
