 Corvino affirms that marriage has an important child-protection function, while rejecting the idea that it is the sole function (192). His key disagreements with Gallagher are over the importance of those other functions and whether there is adequate reason to think that marriage equality threatens the child-protection function. Corvino argues that denying same-sex couples access to the human goods that marriage can provide to them is no small matter for those couples and that Gallagher vastly underestimates what such access means to them (198). Given how persistently and vigorously same-sex couples have fought for marriage equality, it is difficult to disagree with Corvino on the matter.
