I know Cali wasn't being serious when she said Donald Duck in Nazi uniform was scarring, but for arguments sake, let's say she was.
Most young children watching it wouldn't understand how evil the Nazis were.
Obviously as we get older, it becomes a lot more clear.
Seeing Donald Duck in a Nazi uniform isn't as much shocking or traumatic as it is curious.
Curious how in today's society, putting a cartoon character in Nazi garb would draw ire from all sorts of media people.
Even if the cartoon character was mocking Nazis.
Back then, the lack of social media made this scenario a lot less jarring.
