Many people who go against gay marriages whithout using religion as an excuse would say "marriage has always been between a man and a woman." Actually, same-sex marriages occured in more than 30 African tribes before colonial times. Several Roman emperors (ie Elagabalus) married other men. During the Chinese Ming Dynasty (1378 AD - 1644 AD), marriages between two men in Fujian Province were recognized. So what's their argument?
