Justice Anthony Kennedy has been called the most libertarian member of the Supreme Court (though Ilya Shapiro finds his libertarianism “faint-hearted”). So maybe it’s no surprise that in the Lawrence (2003), Windsor (2013), and Obergefell (today!) cases, Kennedy wrote a majority decision finding that gay people had rights to liberty and equal protection of the law.
As I note in The Libertarian Mind and in an article just posted at the venerable gay magazine The Advocate, libertarians and their classical liberal forebears have been ahead of the curve on gay rights for more than two centuries:
As the Supreme Court prepares for a possibly historic ruling, most of the country now supports gay marriage. Libertarians were there first. Indeed John Podesta, a top adviser to Bill Clinton, Barack Obama, and Hillary Clinton and founder of the Center for American Progress, noted in 2011 that you probably had to have been a libertarian to have supported gay marriage 15 years earlier.
Just seven years ago, in the 2008 presidential campaign, Barack Obama, Joe Biden, and Hillary Clinton all opposed gay marriage. The Libertarian Party endorsed gay rights with its first platform in 1972 — the same year the Democratic nominee for vice president referred to “queers” in a Chicago speech. In 1976 the Libertarian Party issued a pamphlet calling for an end to antigay laws and endorsing full marriage rights.
That’s no surprise, of course. Libertarians believe in individual rights for all people and equality before the law. Of course they recognized the rights of gay people before socialists, conservatives, or big-government liberals.
