 Most scholars working in the areas of philosophy and legal theory endorse a principle of equal treatment for same-sex and heterosexual couples and argue that equal treatment requires that same-sex marriages be legalized (Wardle 1996; Eskridge 1996; Balkin 2020). However, there are dissenting voices in the literature, rejecting marriage equality. These voices do not argue in favor the traditional practice of criminalizing same-sex relations, although some contend that such relations are “manifestly unworthy of the human being and immoral” (Finnis 1996: 14). But they all argue that extending marriage to same-sex couples flouts important values and principles.
