“ ‘CNN and MSNBC would be more effective if they occasionally gave the devil his due, instead of mirroring the intolerance of their prime-time counterparts at Fox.’ ”

That’s what retired U.S. Army Lt. Col. Ralph Peters had to say about the other cable-news stations in the wake of his exit earlier this month from Fox News, where he spent years serving as an analyst.

The “devil” he’s referring to is, of course, Donald Trump, whom the lieutenant colonel said deserves some credit despite his “execrable” behavior.

Trump “has done a few useful things, such as facilitating our military’s response to the Islamic State,” he wrote in a commentary piece for CNBC. “But those on the left cannot accept anything good can come from this self-drawn caricature of a devil.”

The same is true for the other side of the aisle.

“The hyper-media’s insistence that individuals are either all good or all bad, on our side or on their side, cripples our democracy,” he said. “President Obama, who I criticized ferociously and without regret, squandered opportunities for greatness, but conservatives could not credit him with doing anything right.”

Peters revisited the impetus for his leaving Fox, while urging rivals in “the ethical wasteland of today’s hyper-media” to avoid a similar fate.

“Recently, I left Fox News, where I’d been at home for a decade, because I believed that its prime-time lineup had become a propaganda arm for a wanton president,” he wrote. “But my despair over Fox does not make its cable-news rivals camps of the saints: In the race for ratings, even those outlets that have not yet fallen into the propaganda abyss often drive right to the edge.”

The tone of his piece suggests Peters would mostly be in agreement with this chart of media bias, which has gone viral in recent weeks:

He echoed the frustrations of many.

“As a news junkie, I cannot rely on cable-news for even a rudimentary understanding of an increasingly interdependent world,” he said. “They’re entertaining us, but they’re failing us.”

His solution?

“Neither liberals, nor moderates, nor conservatives alone can defeat the new propagandists. We all have to pledge our allegiance to proven facts,” Peters wrote. “Ferocious arguments are fine — but they must be tethered to reality. There may be additional facts, but there are never alternative facts.”
