Some take the view that this is fine, that marriage is being protected by keeping two men or two women who love each other from getting married. Well, what is the point of marriage? It is in part to ensure stability in the raising of children and ensure a mutual relationship with the teeth of law. Advantages to marriage for the children of gays and lesbians include such issues as the inheritance of property and of the ability to see one of their parents in a hospital.
Indeed, in far too many places, not only can gay couples not marry but they are barred from adoption. Tens of thousands of children are forced into foster homes because of our attitudes toward gay and lesbian couples.
Well, what about tradition? Tradition is not and never was a reason for injustice and discrimination. America's ideals are not about lesser status for some of its Americans. When interracial marriage bans in the United States were revoked, this was an example of Americans furthering and ensuring the rights of its citizens to marry someone they loved who might not have had the same color skin as themselves, but who they loved dearly.
Today, few folks state that interracial couples should be barred from marriage, but we choose to extend this ban to same-sex couples.
