What are the inherent philosophical presuppositions about the nature of society and about society’s relation to the individual?
“Supporters of same-sex marriage believe that ALL traditional notions about gender, marriage and family result from artificial social institutions rather than from an immutable human nature endowed to us by God or nature. This is the social construction theory of human nature and institutions.
Contrast this with what opponents of same-sex marriage believe to be true. They maintain that sexual egalitarianism, the belief that all sexual practices are equal, is false. They hold that informed consent is not a necessary condition for an act to be permissible legally or morally. And they assert that traditional notions of gender, marriage and family are best understood as the result of moral reflection on human nature and history. However varied these notions have been expressed throughout history, they are part of the furniture of the universe and are essential to maintaining the moral ecology of society.”
