Answer by Rob
The biggest danger homosexual civil marriage presents is the enshrining into law the notion that sexual love, regardless of its fecundity, is the sole criterion for marriage. If the state must recognize a marriage of two men simply because they love one another, upon what basis can it deny marital recognition to a group of two men and three women, for example, or a sterile brother and sister who claim to love each other? Homosexual activists protest that they only want all couples treated equally. But why is sexual love between two people more worthy of state sanction than love between three, or five? When the purpose of marriage is procreation, the answer is obvious. If sexual love becomes the primary purpose, the restriction of marriage to couples loses its logical basis, leading to marital chaos.
