Heck, forget Cronkite, or Murrow, or even Duranty. This whole leftist rot in “objective” news sources (the quotes are meant to indicate sarcasm) was there since Walter Lippmann even formed Objective News Media, and such was by design. Just read up ProgressingAmerica, and you’ll see what I mean by that.
And I’m just going by America alone. If I were to go even farther back, I’d even argue that that whole mess started with the Enlightenment via Voltaire and his cronies when they took over the French Academy in their agenda against Christianity.
You really can trace it all back to the snake in the Garden of Eden. It’s God (good) vs. evil.
