Nope. The decision says precisely the opposite — that monogamy is a civil institution which may not be superceded by religious doctrine.
No, it says marriage is regulated by statutory law.
Homosexuals cannot be monogamous. Mono-'gamy' denotes a biological procreation homosexuals are incapable of with each other.
Aside from that, nature determines how babies are produced. The natural law does not need human laws... All men are born of women.
Monogamy is a religious standard applied to the secular law.
Another convoluted decision like Roe v. Wade.
If Roe v. Wade says society cannot intervene in private reproductive choices, then public funding for abortion is illegal.
The homosexuals want their "separation of church and state," yet they will seek ceremonious sanctification in a marriage rite and some kind of esoteric absolution from the church of the state.
