Same-sex marriage

Katherine Young and Paul Nathanson, both on the faculty of McGill University, have no difficulty with homosexual relationships, but they oppose efforts to expand the legal definition of marriage to cover them. According to the authors,

Because heterosexuality is directly related to both reproduction and survival, and because it involves much more than copulation, all human societies have actively fostered it (although some have also allowed or even encouraged homosexuality in specific circumstances). Heterosexuality is always fostered by a cultural norm, not merely allowed as one "lifestyle choice" among many.
