Since "Words" are one of the forms of human communication, they cannot be broken down or defined as shapes and illustrations, nor can the spoken word be defined as sound from the larynx. And similarly the swastika is not just a placement of color and lines. They are both expressions of thought - communication.

Theatrically (artistically) "The Producers" somehow has been able use the swastika and Nazism to create a humorous presentation that doesn't offend. Go figure.
