The way that I do that personally is to only read news that link to reputable sources (Associated Press, BBC, Reuters, UN reports, Guardian to an extent etc). These also make mistakes or, at worst, are biased themselves, but they still hold journalistic values.
My reasoning is that hopefully an editor has done the moderation before the article goes out, so that I don't have to. The issue with my approach is that I'm limited to the outlets that I'm familiar with, where there might be others out there that hold the same standards.
It would be good to have a sub to aggregate only reputable news sources.
Such a shame... What got me into CoD was the original MW campaign. After that I had to play 2 and 3. Only then o ventured into multiplayer. I haven't really enjoyed any of the other campaigns as much since (with exceptions such as lights out and a couple of the second war ones).
