Hugh Hefner has penned quite the lovely defense of gay marriage in the September issue of Playboy. Here's an excerpt, but do yourself a favor and read his piece in its entirety.
Nearly 50 years ago in the pages of this magazine I warned that "when religion rather than reason dictates legislation, do not expect logic with your law."
Today, in every instance of sexual rights falling under attack, you'll find legislation forced into place by people who practice discrimination disguised as religious freedom. Their goal is to dehumanize everyone's sexuality and reduce us to using sex for the sole purpose of perpetuating our species.
To that end, they will criminalize your entire sex life.
