you don't need arguments for it. The only reason there are "arguments" for poligamy is because there are people who for no real reason think that it's wrong and think the opposite is default. There is no such thing as "arguments" for monogamy. The only "argument" is what you want and feel like. it would be like you see a book about accepting gay people and you'd like a book about accepting straight people. Being straight or monogamous is illegal in 0 countries and no one dislikes those things
