It means showing people not living in a monogamous stable relationship dedicated to upbringing of their kids, that it is "normal". I'm not a homophobe, so I guess I won't fuck off, asshole. I have nothing against gayness, I am actually a bit bi, also unmarried. However, I know that if everyone lived the way I do, this society would be MUCH, MUCH, worse off. Therefore I would not advertise my lifestyle and tell people it is okey, and they should live it.
Your lifestyle is ok, dude or dudette. Seriously. It is systemic problems of societies such as horrbile education system, emotional politics and various instances of "prisoners dillemma" games that are much more major factors that are detrimental to society well-being.
