"What's happening now is a wholesale repudiation of the 1990s move to eject gay people from the American family, writ large. The reason for DOMA was anti-gay animus by a group of men who showed their respect for marriage by divorcing multiple times and having affairs. The reason to undo DOMA is a rejection of that animus, and the growing recognition there is no way to argue against same-sex marriage that is not ultimately an argument for the moral inferiority of gay people. As of Friday, only four Democrats in the U.S. Senate had not come out in favor of gay marriage. "I have concluded the federal government should no longer discriminate against people who want to make lifelong, loving commitments to each other or interfere in personal, private, and intimate relationships," Sen. Heidi Heitkamp of North Dakota said. "I view the ability of anyone to marry as a logical extension of this belief." The reason to not support gay marriage is the lingering sense that there's something strange or not right about it. That it's fine for gay people to do what they want in privacy, but that their relationships are not the same as straight ones. Not as powerful, not as loving, not as legitimate. "[T]his is the inevitable extension of my efforts to promote equality and opportunity for everyone," said Sen. Mark Warner in announcing his new views. "[A]s many of my gay and lesbian friends, colleagues and staff embrace long term committed relationships, I find myself unable to look them in the eye without honestly confronting this uncomfortable inequality," observed Senator Claire McCaskill in a Tumblr post."
