Any viewer should regard anything anyone says on TeeVee with a great deal of skepticism.
Any reader should regard anything they read on any news site or anywhere on the internet for that matter, with a great deal of skepticism.
But libs are far less likely to do that when the anti-Trump / anti-anything-non-lib-approved talking point from their 'trusted' sources, because they want to believe what they're being told.
And that, is not being objective. Skepticism is at the heart of objectivity.
