Herman and Chomsky effectively disproved the notion that mainstream media gives "balanced" perspectives on news in Manufacturing Consent. The trouble is that media has a massive reliance on government institutions for sourcing information and advertisers for revenue. The way that information is withheld from government sources in the case of dissent from doctrine, or money is held back from corporations in the case of dissent from their interests creates patterns and frameworks of self-censorship and framing that twist information. None of this means our news networks are evil, but they are subject to the rules of the game and the only reason they are still going today is because they learned to play ball.

You can question the lack of a perspective in reporting, or doubt the framing of provable information without losing faith in the system. It should almost be seen as your job as a responsible news-reader to look past the propaganda (i.e. systemic limits on information conveying) as best you can, while not becoming entirely jaded or entirely untrusting.
