This document contains two arguments against gay marriage. The first argues that children need both a mother and father to become healthy and successful, and that legalizing gay marriage could undermine traditional marriages. It cites sources claiming mothers provide unique nurturing to children and that children with absent fathers are more likely to experience early puberty or teen pregnancy. The second argues that legalizing gay marriage would further confuse people about the importance of marriage and would undermine an institution essential to society's well-being and stability. It questions whether legalizing gay marriage would destroy the sanctity of marriage.
