 Congresswoman Chisholm's delivery that was so inspirational because

D. She incorporated stereotypes into her speech.

In her speech, she went straight to the point. She did not use any highfalutin words to sugar coat the bitter truth that women are being stereotyped. Example of this stereotype is "The happy little homemaker and the contented 'old darkey' on the plantation were both produced by prejudice," 

Stereotyping is what most people do without even knowing it. It is not a subject that everyone can bring up in the middle of a conversation and become its focal topic. 

Her speech awakens the consciousness of people that they have been stereotyping people unconsciously. Thus, prompting them to do something about it.
