Tens of thousands of people protested against France's new gay marriage law in central Paris on Sunday. The law came into force over a week ago, but organizers decided to go ahead with the long-planned demonstration to show their continued opposition as well as their frustration with President Francois Hollande, who had made legalizing gay marriage one of his keynote campaign pledges in last year's election.(AP Photo/Thibault Camus) ( France Gay Marriage )
