"What incels can learn from Simone de Beauvior" is an all-timer topic for an essay but anyway this has some good sections

Finally, what does Beauvoir have to say to incels already in the grips of this delusion of sovereignty? Importantly, quite a lot. Although Rodger was fully consumed by self-alienation, it is not too late for many men to live better lives. According to Beauvoir, this requires a kind of “conversion.” They must renounce the vanity of viewing themselves as fallen gods, and assume the risk of existing as human beings. This involves moving away from an appropriative, conquering attitude toward a stance of openness and reciprocity. It requires cultivating a healthy sense of competition and fair play, of personal responsibility, humility, “friendship and generosity”. It also means foregoing the certainty of a world with fixed hierarchies—including those based on race and class—and viewing interpersonal relations as always to be made and remade. To relinquish sovereignty, a man needs to accept that, in addition to being a freedom, he is part of Nature and of other people's plans, that he is a body and a history that can be evaluated. Importantly, he needs to accept that there is no action without judgment, and no praise without risk.
