Defendants' essential contention is that bans on same-sex marriage promote the welfare of children, by encouraging good parenting in stable opposite-sex families. . . . Defendants have presented no evidence of any such effect. Indeed, they cannot even explain the manner in which, as they predict, children of opposite-sex couples will be harmed. Their other contentions are equally without merit.
Those who get stuck doing the same things for too long are bound to get left behind the strong who press on and re-invent themselves.
