“Just think of all the wartime cartoons you don’t see anymore”
Popeye fighting the Japanese and Superman fighting the Germans (while eating spinach in the face of rationed meat). Never to be seen again, along with all the Westerns that showed that individuals could live using their own morals without a strong Central Government.
And all the wartime stuff Bernays and the proto-Disney cartoonists put out.
Down the memory hole.
And Song of the South? You are correct, never. Elmer Fudd? Speedy Gonzales? Probably even Mr Magoo!
"Hey, Pancho!" "Hey, Cisco!"
