All I can ask from society is that it please stop telling me why I should like sports.
Americans don't need a metaphor for war. We have war. If anything, we use war as a metaphor for sports.
As you know, the thing that I know the least about is the topic of sports.
Sports is a bloodless rehearsal of confrontation, and everyone shakes hands or high fives or fist bumps at the end to show that everything is okay.
