I might be as naive as Siamak think you to be, but from another angle. I have always thought that journalists are supposed to be objective. You have stated, on this page, that you are as "antidMcD" as other people.You do not think that the reson for the editor to ban your article, could have something to do with your personal views coming through in your piece? I think this most likely!
I, which probably will not come as a suprise to you, applaud your editor. He took his editorial responsibility seriously. I just wish more editors would do this, regardless of the subject. You should be allowed to write your piece, but it should be objective and should not contain slander.
