Define 'casual sex'. (Perhaps define the opposite too.) And then, think across the breadth of the American people you know and all those other people you don't - across different ages, places, religions, circumstances, etc. And then say that tell me you know that 'casual sex' is the general behaviour and attitude of everyone. And then, go back to the original point for a bonus, and consider what you know about the general behaviour and attitudes are of the people in England 400 years ago.
