Which is an impossible hope.
Marriage is the legal framework surrounding a biological imperative--which is the mating behavior of heterosexual humans that exists to guarantee the next generation. Since the entire gay lifestyle is built around the absence of that biological imperative, there is no reason to believe that they will suddenly behave as if they are subject to it because they can now get a legal document.
I've read that gays who have long term relationships continue to engage in the promiscuous lifestyle. It seems to be a characteristic of the culture.
I know it is an impossible hope; the problem isn’t a “characteristic of the culture” but a symptom of the illness.
