Paper Topic

I am thinking about doing something along the lines of the satirization of religion in both film and plays, along with some critiques and reviews of these works. My thesis is going to slant towards the way that most people who write religious satire and either non religious, or have gone away from a religion that they were brought up a part of. On the other hand, many of the critics of these works are often hard core religous groups or individual religous zealots and my thesis is going to try and find a way to attack both sides of the argument and come up with some sort of middle ground for commentary and satirization of religion, especially in present day america where a high number of people claim to be religious and particularly christian, but their lives dont necessarily follow that premise. I want to look at things like political elections as well, but i dont want my topic to be too broad or to jump around during the paper so i was hoping that maybe someone could help me out with a concentrated thesis that could somehow incorporate all of these things. I was thinking something along the lines of using a movie like bulworth or election and showing the political satirization aspects in films, and how religion seems to be an intrugal part of the election process nowadays. I have alot of ideas, but im just not sure how to focus in on them to create a cohesive thesis and a clear paper. Any ideas would be greatly appreciated.
