This argument, that same-sex marriage somehow undermines “traditional” marriage, never really made sense to many Americans, for good reason. Since conservatives would rarely define what they meant by “traditional”—saying that it’s about a man and a woman and declining to elaborate beyond that—it ended up sounding like they were saying that if gay people were allowed to marry, then straight people would all get divorced or something. […]

In reality, however, there was a subterranean argument that actually is logical and makes perfect sense. It was never just about man-woman marriages. The tradition that is disappearing is the belief that marriage is a duty, especially for women.

[… W]omen in modern society no longer feel like they have to be married to be granted entrance into adult society. Single women living by and supporting themselves is no longer considered scandalous. Marriage is, bit by bit, becoming more about a partnership between equals who choose each other for the purpose of love and happiness. Which means it’s becoming less about giving men control over women’s lives. […]

To accept same-sex marriage is to accept this modern idea that marriage is about love and partnership, instead of about dutiful procreation and female submission. Traditional gender roles where husbands rule over wives are disintegrating and that process is definitely helped along by these new laws allowing that marriage doesn’t have to be a gendered institution at all.

–Amanda Marcotte on marriage equality.

True to its name, marriage equality benefits everyone. Except maybe gross conservative men who… are secretly afraid no woman would ever love them unless they were forced into it by SOCIAL PRESSURE? Or something? Who even knows.
