These criticisms of Singer on the quoted website (and I am not supporting him as I know little of his ideas at first hand) come from someone who has attacked Obama thus "In case you hadn't heard, D'Souza wrote a piece about the president in Forbes magazine. "Incredibly, the U.S. is being ruled according to the dreams of a Luo tribesman of the 1950s," he wrote. "This philandering, inebriated African socialist, who raged against the world for denying him the realization of his anticolonial ambitions, is now setting the nation's agenda through the reincarnation of his dreams in his son."

As can be seen (from my example too), it's easy to produce quotes supporting particular positions rather than engaging in considered debates.
