Argument: Denying marriage to infertile would be too costly
Adam Kolasinksi. "The Secular Case Against Gay Marriage." The Tech (M.I.T.) February 20th, 2004: "A small minority of married couples are infertile. However, excluding sterile couples from marriage, in all but the most obvious cases such as those of blood relatives, would be costly. Few people who are sterile know it, and fertility tests are too expensive and burdensome to mandate."
