Maybe it's because "Journalism" is just another label, and labels only describe avatars, but we're dealing with actual people. The way I see it, "Journalists" is no different from "Consultants", "Bloggers", "Fate", "Time", "God", "Devil", "Americans", "Russians", "Straight" or "Gay" - it's simply in the nature of generalizations (labels) to describe, at best, avatars, but in the privacy of our actual hearts and minds, we each have our own.
PS. In the US I'm sometimes told I'm not a typical American, in Switzerland, that I'm not a typical Swiss (I have dual citizenship). The objective truth (lol), well, my truth anyway, it's not about me, it's about their avatar :-]
