The arguments they put forth against same-sex marriage usually include the following:

marriage is a fundamental and unchangeable institution, marriage is traditionally between persons of opposite sex, if same-sex marriages are recognized then bigamous, polygamous, incestuous marriages and marriages with animals must be recognized too, same-sex couples can't have children, society has an interest in promoting marriage as the environment for procreation and child-rearing, same-sex parenting is less good for children than the parenting found in traditional family units, same-sex parenting may bias children towards a homosexual lifestyle, same-sex relationships are less stable and less faithful than opposite-sex relationships, allowing same-sex marriages will damage the institution of traditional heterosexual marriage, marriage is defined by scripture and tradition as involving a ma
