Their is an excellent article in "The American Conservative" about storytelling and the fact that storytelling in America is the domain of liberals. They tell the stories through books, TV shows, and movies that have shifted public opinion in a leftward direction. Gayness has become mainstrain largely because of Glee, Will and Grace, and Modern Family. These stories made us care about these gay characters. All the political rhetoric in the world could not accomplish as much.
Now there are plenty of stories conservatives could tell. It is unclear whether they have the skill to tell them or to move beyond black and white depictions of the human condition. As long as conservatives are disinterested and largely ignorant of our popular culture they will continue to be on the losing end of things.
