But I have seen it done so many times. Writers take a work of fiction such as a book or movie where the author generally has a similar outlook and use that to draw lessons. You see that a lot on the left, as well as on the right with Ayn Rand's Atlas Shrugged. I don't think it is convincing anyone. Anybody can write a book where the people they admire become heroes and the policy they espouse has a good outcome, or the people they despise become villains and the policy they are against leads to bad outcomes. How close the book universe is to the real universe is a different story.
