I'll be brief. I promise.
2:05 into this video Pierre Gleizes is asked if he is a journalist or an activist. He believes he is both. While I consider him an activist I do not consider him a journalist. He is paid by Green Peace, whos goal is to "use peaceful direct action and creative communication to expose global environmental problems and to promote solutions that are essential to a green and peaceful future." If you are being paid by an organization to further an agenda you are not a journalist, even if that agenda is noble. Essentially you are in the business of marketing.
