I find it amazing that often when the subject of same-sex marriage comes up someone always cries "Oh won't someone think of the children!?", without realising that by discriminating against established same-sex couples who already have children (which of course is quite legal), they are in fact discriminating against those children as well. In that, by not allowing the parents to marry, you are telling the child that their family is 'abnormal' and 'wrong'.
