This is not about homosexuality as the homosexual deserves the same respect and the same rights as does any other citizen. Nor is this about committed homosexual relationships as such relationships deserve respect and should be encouraged. It should be acknowledged that same sex committed relationships, whether or not the term marriage is employed, have proven to work out fine for most of those who have chosen to participate in them. The main argument for legal recognition of same-sex relationships as marriage has been that the partners involved deserve the same access to public services as do married couples. It should be acknowledged that this is a real issue that should be legally addressed. Yet clearly such questions as access to services for gay couples are resolvable without necessarily passing a law that declares gay relationships as marriages.
Let’s be blunt with no offense intended. Two people of the same sex cannot be married because two people of the same sex cannot physically consummate a marriage…
