Bennett was a combat vet of WW2, and he participated in vicious house-to-house fighting when the Allies crossed the Rhine and pushed into Germany.
Bennett has said that the experience turned him into a pacifist. I wonder if some people turned the word "pacifist" into "doubter", and that's the source of what you heard.
As for me, I'll give the old vet a pass on his political views.
Maybe so. He was there, not me. I haven’t the faintest notion of what that battle experience must be like first hand as a young G.I.
Yes. There is a difference between the two words pacifist, and doubter. They are not necessarily interchangeable.
