I don’t buy it but…
In an issue of Superman released early in 1943, the superhero protects American navy ships from deep-sea creatures under the control of a Nazi agent. Superman manages to defeat the creatures and their master when the whistle used to control the monsters breaks and they turn on him.
I know a lot of deep-sea creatures, a few are even my friends, and this is just slander.
In fairness to the creatures, the comic is not suggesting that the creatures are Nazis themselves, just that the bad guys were mean and controlled their minds in an immoral fashion.
Point taken.
This makes perfect sense now…most of the birds I know are Communists.
