"Dear Madame de Beauvoir" is a response to the book "The Second Sex" by the French philosopher Simone de Beauvoir. The book tackles existentialist feminism, exposes the flaws in radical feminism, and provides essential tips for our daughters to navigate safely the world created by men. The book introduces essentialist feminism, a new school of thought within the feminism movement that sees man and woman as inseparable entities living in an obligatory symbiotic relationship. They are joint heirs and co-equal in managing the material universe. They have never been in war, as anarchist feminists depict it, but in lovely relationships that sometimes do not end well. Man and woman complete and complement each other; they can switch tasks in the house as they please, but roles cannot be abolished because we cannot have two captains in one boat. The two individuals live as pilot and co-pilot and cannot leave the house simultaneously because the ship cannot be left unattended. Essentialist feminism promotes function-based roles in the marital home to address the nascent confusion in marriage instead of the gender-based roles we traditionally practice.
