Dana Stone Denise: John Clark calls gay marriage a distraction from the purpose of being wed, which he says is procreation. Perhaps we should just invalidate the marriages of infertile couples because, after all, they have no children. And if one marries only to procreate, why do people enter into second marriages well after their childbearing years have ended? Procreation is one of several different reasons to marry, and should not be used as a defining factor or prerequisite.
