Yes, finding truth in all the hype (from both sides) is quite difficult. And pulling your "facts" from just the side you find most agreement with, limits your reach, and puts you in the same trap of the many of the proponents and followers on "the other side". And since none of us can be experts in all subjects, we do need to figure out how to get information we can trust. So, what do you do?
One thing you can do is consider the source - does it appear to take a balanced approach, or is it all one-sided. In other words, what is the agenda. Another consideration - is the information coming straight from the source, or is it being reported, out of context (and possibly twisted), to fit the aims of the reporter? Then too, there is the point you mentioned in your question - what do OTHER expert sources have to say in this regard - is it the same, or something different?
I believe that using the above principles, you can begin to find ways to separate truth from spin, and also discover sources which don't necessarily have a "stake in the game." But even at this point, don't blindly accept something you see or hear, even from previously "neutral" sources. Sometimes even with the best intentions, and real efforts to provide balanced reporting, your previously "neutral" sources can get it wrong.
Yes, finding the truth can be quite difficult, but that work is part of our duty to be informed citizens. You are to be commended for taking part in this struggle.
