Unbiased Opinions (oxymoron)

My professor has assigned an essay in which I am supposed to respond in an eloquent and insightful manner using my text book as a primary source. However, I cannot. The authors of Computer Mediated Communications are so biased that I immediately doubt every conclusion and judgement that they make. Even the list of resources at the end of each chapter I doubt since I cannot believe they would actually include anything that may counterargue the topics they address. It's like reading the most ra-ra self-help book, everything is great only if a person follows these simple steps.

I also have a difficult time selecting a topic for examination since I DON'T know enough to begin guessing where and how I might begin researching topics without having to wade through a bunch of garbage, wasting my time when I need to be writing my paper. The obvious choice which would have a HUGE selection of research would be internet and pornography. But I don't want to do this since I already have an opinion in which i would consciously and unconsciously select information that would validate this opinion. I could not offer an objective critique, therefore becoming the very thing I am railing against. I almost feel insulted by the authors and how they address me.
