 According to Robert McChesney, healthy journalism in a democratic country must provide an opinion of people in power and who wish to be in power, must include a range of opinions and must regard the informational needs of all people.Many debates centre on whether journalists are "supposed" to be "objective" and "neutral"; arguments include the fact that journalists produce news out of and as part of a particular social context, and that they are guided by professional codes of ethics and do their best to represent all legitimate points of view.Additionally, the ability to render a subject's complex and fluid narrative with sufficient accuracy is sometimes challenged by the time available to spend with subjects, the affordances or constraints of the medium used to tell the story, and the evolving nature of people's identities.
