Gay marriage is good for society  Gay marriage has clear and tangible positive effects on societies where it is permitted. There are now ten countries that allow gay marriage, with no obvious or noticeable detriment to society at large. As Chris Ott reports from Massachusetts, one of few US states to grant gay marriage rights, ‘predictably, the sky hasn’t fallen…ensuring equality doesn’t mean there’s less to go around for everyone else’ 1. Further to that, gay marriage encourages gay adoption, granting a home and a loving environment for an increasing number of orphaned or unwanted children worldwide. The evidence also suggests that gay parenting is ‘at least as favourable’ as those in heterosexual families, eroding fears that the adopted children will be worse with gay parents 2 . The economist Thomas Kostigen also argues gay marriage is a boost for the economy, ‘weddings create revenue of all sorts…even if a marriage doesn’t work out that helps the economy too. Divorces cost money’ 3. Finally, and most simply, societies benefit from the net utility of their citizens, to allow and even encourage gay marriage ensures that those gay citizens wishing to celebrate their love are able to do so, in an environment conducive to their mutual happiness.  1.
