What is the predominant assumption above love in American society?
I meant to ask, "What is the predominant assumption about love in American society?"
why is your second post an exact duplicate of the first?
As for the question, if you ask fifty people, you'll probably get fifty different answers. Love such a subjective emotion that trying to project it onto society is sure to produce pushback and differing opinions.
Have you any thought of your own on the matter? You don't have to feel compelled to justify them, just explain them in a rational and consistent manner.
