Besides the obvious empirical weight of your condescending dismissal I have yet to see any evidence that states it is impossible to report the news without an opinion. In fact, if you open the NYT you will find it divided into sections on opinion and factual news.
Give me some evidence of main stream media reporting opinion with news. Give me a non-opinion piece newspaper article that has opinion.
You should check out Manufacturing Consent by Noam Chomsky. It's a classic book on this topic.
how about this: some time ago when the news that tortures did not produce any valuable intel to counter terrorism was wildly reported in USA, the Polish media instead run a story about how terrorists were planning attacks in Poland during mayor holidays. See: no real opinion is conveyed here explicitly, but by controlling which and when facts get reported you get the same result as directly stating the opinion (in this case defending the need for doing nasty things to fight terrorism).
