Polyamory, polygamy, or whatever you want to call it, increases the number of naked bodies you're legitimately going to be allowed to see and touch, whatever your sex or sexual orientation.

The study examined the health outcomes of people who are divorced, as well as unmarried, cohabiting couples. Published in the American Journal of Public Health, the research has implications for younger generations, as more people pursue unconventional relationships and divorce continues to be an option.
The Christian Post has such an article: "Why Two? The Question Gay Activists Can Not Answer." The author, Michael Brown, wrote a book on how Christians will reverse the course of the "gay revolution." No doubt he believes the Second Coming is just around the corner as well. Good luck waiting for either.

Look at what the status quo means: Gay couples separated in hospitals. Losing their life savings when one passes away. Having a marriage license revoked when they cross state lines.
Maybe it is futile to try to explain this to Justice Moore. Would he ever be able to understand that someone who is bisexual is capable of monogamy? Or that gender identity is not linked to sexual orientation? Or that incest is not the same thing as homosexuality? Trying to explain these concepts to Roy Moore is like explaining string theory to a clam.
