This is not surprising from the 'gay president'.

Obama opposed California's ban on gay marriage. He generally has said he supports equal rights under the law for same-sex couples. Some religious conservatives said the choice of Warren showed Obama was willing to reach out to them.
Robinson said he advised Obama several times during his presidential campaign.
"I was very early on taken with his anti-polarization message," he said. "So part of the invitation came out of the albeit brief relationship that we have had."
The 77 million-member Anglican Communion, a global federation of national churches, has been in upheaval since 2003 when the Episcopal Church consecrated Robinson as the first bishop known to be in an openly homosexual relationship in more than four centuries of church history.
The Episcopal Church is the U.S. branch of the worldwide Anglican Communion.
Joe Solmonese, president of gay rights advocates the Human Rights Campaign, called Robinson's selection "encouraging."
"Bishop Robinson models what prayer should be -- spiritual reflection put into action for justice," he said.
Robinson, who last year entered into a civil union with his longtime partner in New Hampshire, said his prayer would focus on inclusiveness.
"It will certainly be a message that everyone in the nation can identify with. And part of the prayer will be for President Obama but also I am going to include words of prayer for the nation and what I think we are called upon to do," he said.
