I'm confused why you imagine that masculine socialization and gender indoctrination in our specific culture is made up of immutable characteristics. Masculinity looks different in different cultures and at different periods of time - something that ought to be perfectly obvious to anyone as intelligent as you are - particularly when you are responding to a story about masculine norms - not inherent masculine traits (of which there are zero).
"In cultures where there is no historical belief in male dominance, or coercion and violence as a demonstration of masculinity, rape is nearly unheard of. In fact, in at least some of these cultures, rape is seen as shamefully unmasculine behavior. The Minangkabau of Indonesia, the world’s largest matrilineal culture, is a place where men move into their wives' homes after marriage. It is also a place where rape is largely unknown, in part because it is considered unmanly."
"In the 17th and 18th centuries in England, masculine men were expected to be in touch with their “sensibilities” by sharing and expressing their most profound feelings. In fact, weeping men were often the heroes of popular novels."
