The point is to devalue religion's influence on the greater population by bastardizing one of it's holiest tenets. Gay marriage was never about two consenting adults living together how they want. It was always about the destruction of religion and the nuclear family and through them ultimately the country.

And THAT is a reason to oppose this trend, no matter how liberal you are and how much you don't give a damn if gay people get married. Especially when we've found a sanctioned Russian state bank attached to at least one of the signers, and another is a foreign power ("Sir").
