I've seen this "is not a real news source" on both sides. From the right it's often cast as MSM or liberal media bias.

This attitude is destructive as it's making it so difficult for us to come to any agreement on what we accept as a trustworthy third-party. Where do we start to give people some benefit of the doubt? As it is, even "trust but verify" can appear impossible. I'm not advocating some "can't we all be friends" platitude. As a practical matter, how do we move forward from here?

Edit: minor wording changes to remove generalization and grammar improvement
