It is not about gays enjoying the same rights as straights it never was. It is about the extreme left wing destroying Capitalist petite bourgeoisie society or bourgeois morality.
If everyone had to sign a marrage contract negotiated by two law firms setting out all the rights, benefits and responsibilities of each party before they walked down the isle, no gays would want to wed. In fact I doubt that many 'straight' types would either. It is just the religious nature of marrage that attracts the kind of attention from gays, that blood in the water attracts from sharks.
