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.
