As far as the "news" in concerned, let the buyer be(a)ware (to paraphrase an old saying).

In other words, if you get your news from Rush Limbaugh you should do so knowing that the news is heavily slanted to a very conservative bias. If, on the other hand you get your news from National Public Radio you should realize that there is a liberal bias to the news. There is no organization that is able to provide just the facts. Human languages and the brain are not designed to allow one to speak without inserting his/her own biases into the words. These biases cannot be completely edited out and most people don't even try.
