Playboy boss Hugh Hefner has become the latest US star to announce his support for equal marriage.

While he may not be the greatest example of heterosexual monogamy, the octogenarian publishing veteran is adamant that denying same-sex couples the right to marriage is a basic infringement of their human rights.

Writing for Politics.com, the 86-year-old scolds social conservatives for attacking the measure and says: “The fight for gay marriage is, in reality, a fight for all of our rights. Without it, we will turn back the sexual revolution and return to an earlier, puritanical time.

“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.”

Hefner concludes by saying that the US “is a religious nation, but it is also a secular one … No one should have to subjugate their religious freedom, and no one should have their personal freedoms infringed.

“This is America and we must protect the rights of all Americans.”
