Gay marriage is a social positive and enfranchisement strengthens the institution.

Jonathan Rauch

"Domestic-partner and other marriage-lite arrangements, as I can't resist calling them, do not give homosexuals what they need. They also don't give society what it needs. Although not necessarily calamitous, a multitrack featuring marriage and various forms of pseudomarriage is, at best, a distant second choice to same-sex marriage - not just from the homosexuals' point of view but from society's. As for the privatization approach, it is probably the worst option of all. The two approaches fail, at bottom, for the same reason: they misapprehend what marriage is. One sees marriage as a contract between two people. The other sees it as a package of benefits. Well, marriage is indeed both. But it is something much more."

Tucker Carlson

"I'm just for marriage generally. I'm for people making a lifelong commitment. Do you know what I mean? I'm not against gay marriage, actually, and I'm the most right-wing person I know."

Tucker Carlson​, The Ed Show (July 24, 2007)

David Brooks

"When liberals argue for gay marriage, they make it sound like a really good employee benefits plan. Or they frame it as a civil rights issue, like extending the right to vote. Marriage is not voting. It's going to be up to conservatives to make the important, moral case for marriage, including gay marriage. Not making it means drifting further into the culture of contingency, which, when it comes to intimate and sacred relations, is an abomination."

David Brooks, The Power Of Marriage, New York Times (November 22, 2003)

Jonathan Rauch

"America needs more marriages, not fewer, and the best way to encourage marriage is to encourage marriage, which is what society does by bringing gay couples inside the tent. A good way to discourage marriage, on the other hand, is to tarnish it as discriminatory in the minds of millions of young Americans. Conservatives who object to redefining marriage risk redefining it themselves, as a civil-rights violation.

There are two ways to see the legal marriage of Del Martin and Phyllis Lyon. One is as the start of something radical: an experiment that jeopardizes millennia of accumulated social patrimony. The other is as the end of something radical: an experiment in which gay people were told that they could have all the sex and love they could find, but they could not even think about marriage. If I take the second view, it is on the conservative – in fact, traditional – grounds that gay souls and straight society are healthiest when sex, love and marriage all walk in step."

"Gays and lesbians want to get married. Imagine, respect for an institution increasingly ignored by others."

"Children raised by same-sex parents are healthier and happier. A new Australian study suggests these children have better health and wellbeing than children from traditional families."
