My Father called Donahue a "bleeding heart liberal." looking back on what I remember of him - he was a 1970s fore-runner of the simp male Karen of our present age, or as much as society of that time allowed such a figure to exist.. But you are correct, he was not hateful or arrogant and conducted civilized debates
In retrospect, it was a breathtakingly short slide from Phil Donahue through Larry King to Jerry Springer to Hell.
