Filtered. Meaning someone who shares your opinions synthesizes it, then delivers with a comfortable interpretation?
No. To say that true (important, meaningful) conflict in thought becomes apparent only through many individuals. What you've described is the exact method used by MSM, and even worse is that they've conjured those alleged opinions to begin with. As though it's a ready-made thing with no thought required.
If you figure we've got the same interest, as common Americans, then something's there to serve as common ground. MSM's whole trip is to make us believe that ground doesn't exist. It's why their output seeks to avoid stirring thought.
Specific source? We've heard about the 99% who suck, tell us who doesn't.
As a One Stop Announcement Shop, like we're used to with MSM? I don't know if one exists, or could ever exist that way, since it goes back to what you say about a one-sided view.
The glimpses of reason I've seen tend to be on individual issues, and almost always involve challenging the claims made by MSM. Because for all the pretend "differences" between, say, FOX and MSNBC, the message is a unified voice for the same group. A group which happens to be the one that does not share ground with us, has never shared ground with us, and more than anything would like to blast that ground off the face of this earth.
