Walter Cronkite was an opinion journalist. He chose what to report on, and what not to report on. And any number of issues and injustices were ignored by him, not even out of malice or indifference, necessarily. Just lack of awareness, which every human suffers from, is enough to make the idea of "objective" news nonsensical.

News is, and always will be, a two way street. Yes, the journalist must use the utmost caution to be factual and at least acknowledge other perspectives, if only to poke holes in them. But the news consumer must also do their due diligence. Believe no one person fully, diversify your sources, and spend the time to get as full a picture as possible

Refusing to spend that time and simply blaming the media is a chickenish way to absolve oneself of responsibility.
