Exceptionalism or inequality

French Interior Minister Claude Gueant, who also holds the immigration portfolio, caused political uproar by claiming that not all civilisations are equal, with some more advanced than others. "Contrary to what the left's relativist ideology says, for us all civilisations are not of equal value," Gueant on Saturday told a conference in the French parliament building, but closed to the media. "Those which defend humanity seem to us to be more advanced than those that do not," he argued in his speech at a meeting organised by a right-wing students group. - AFP
Why would all civilizations be equal? They evolved separately. What is this universal standard we might speak of, whether equality or a superiority? Adaptations vary. And why is this so demonized?
