To match the rhetorical strategy used by Patrick Henry in his "Give Me Liberty or Give Me Death" speech, Shirley Chisholm could add a sentence that emphasizes urgency and a call to action regarding women's rights.
A suitable sentence might be:
"This injustice must end, and we must rise to demand the equality that has long been denied to us!"
This maintains the passionate and urgent tone of Henry's speech while addressing the need for immediate action for women's rights.
