It was drawn to my attention today that the gay marriage issue is not merely a controversy among American social conservatives, but that the debate rages in other countries too–namely France, in which recently there have been mass protests against Francois Hollande’s plan to legalise homosexual marriage and adoption led by the French political right and various catholic organisations in France. The French left was characteristically flamboyant in its counter-demonstrations, but the point still hits–there are large numbers of people in the stereotypically progressive European countries who take issue with left leaning social reforms. This does raise a question that I think is worth answering. What are the arguments for and against gay marriage? Is there anything to either set?
