In "The Complete Persepolis," Marjane Satrapi shares her experiences growing up during and after the Iranian Revolution. One of the poignant lessons she conveys is the importance of asserting oneself in the face of aggression. This lesson highlights the need for individuals to stand up for their rights, especially when confronted with hostility or oppression.

The quote "I learned that you should always shout louder than your aggressor" encapsulates this theme of resilience. Satrapi emphasizes that, to combat oppression, one must find their voice and refuse to be silenced. This notion of empowerment resonates throughout her narrative, illustrating the struggles and triumphs of those who fight for their dignity and identity amidst challenging circumstances.
