Why is she called a journalist?

If journalists have to be non-partisan by definition (according to the "bloggers can't be journalists" school of thought), then why does the press keep referring to Giuliana Sgrena as a journalist? She works for a nakedly partisan newspaper-- Il Manifesto -- the voice of the Italian communists. If she is a journalist, isn't Jeff Gannon?
