"Homosexual marriages deny children the right to either a mother or a father and are therefore not in the best interest of children." Not a cogent argument. In case you haven't noticed, heterosexual divorce, fathers running off and leaving their children in the care of just the mothers, and out of wedlock child birth also leave children without a mother and father. If this is the main concern, why not work more actively to prevent divorce, child abandonment, and out of wedlock childbirth. Further in a same-sex relationship there are NO unwanted children; gay people have to work very hard and plan well to have children in their homes.
