Ryan Anderson (in response to this question from the Deseret News)
Same gender marriage defines men and women as exchangeable units, and requires that Government institutionally endorse and promote that uniformity, making gender complementary obsolete - especially for children. This definition removes from the law a child’s right to have a father and a mother, and denies the indispensable functions that mothering and fathering provide. Removing gender requirements from marriage further threatens all gender based rights affecting alimony, presumption of paternity, custody battles, the draft during war time, even privacy in public locker rooms, restrooms and showers, all of which depend on the recognition of our unique gender needs.
