Now that the law has changed to teach that marriage is whatever consensual relationship you find most emotionally fulfilling, people will start to believe it, and then they’ll start to live accordingly. They will be more receptive to sexually open relationships, or temporary ones, or multiple-partner ones, as their appetites and fancies dictate. You don’t have to take my word for it. Many proponents of same-sex marriage are gleefully predicting just that. The result will be less family stability, which hurts children and women, and especially the poor.
