“Nothing so terrible has happened in Massachusetts or Canada, so let’s just have same sex marriage.”
Marriage is the social institution that connects generations to each other. Redefining marriage changes the basic structure by which the generations relate to one another, including who counts as a parent. We will not experience the most significant consequences of redefining marriage in the first five years. The most significant consequences may not be the most immediately obvious. It will take a full generation, a full thirty years or more, before society will feel the full impact of redefining marriage.
People making this argument don’t understand the full social significance of marriage. They are ignorant of how social systems actually work.
“Nothing so terrible has happened” is truly an idiotic comment.
