A family can be two men or two women with children; the younger generation is more familiar with this definition. Mitt Romney seems to believe in only a man and a woman (where does he stand on any gay rights)? The Mormons did have a problem with polygamy, and when Utah became a state, they did have to follow the law against polygamy. I don't think accepting gay marriage will lead the way to accepting polygamy, although this is an argument being brought forth.
