This is untrue. What your journalism professor should be telling you is that writing for a newspaper teaches you subtlety by requiring you to express opinions covertly. Pick up any newspaper, local or otherwise, and you will see this to be the case. The opinions are there disguised, incognito. They flit about the edges of tangibility without ever crossing into the no-fly zone of editorialism.
Words are the key.
They are tools, and how they are used makes all the difference between a Pulitzer Prize and a libel suit. Not knowing what you re talking about is a hallmark of the professional writer, as P. J. O Rourke will tell you if given half the chance and a double gin. This is a fact I learned almost immediately after switching my major from business administration to English, a major career move for me as a writer. I wanted to not know what I was talking about in English class, too, thus doubling my field of un-knowledge. So basically what I m trying to say here is come on down to the office and sign up.
