I’m glad Walter Cronkite is remembered through that school. In my mind, he was one of the last great journalists from an era that wasn’t strongly politically biased.
When I read that I'm always personally confused. He had a commanding voice and had an aurora of being above it all. But when you listened and watched what he actually did, he seemed very political in my mind, though perhaps more of a moderate(?).
He even advocated for world government, endorsed politicians, etc.
Uncritically accepted the Warren Report.
Is it possible you think there's a stronger political bias in the media today than in the past because of proganda designed to make you think that?
