Role models for example. Movie heroes, book or video game protagonists are predominantly male. That shapes perception and expectations of desired and acceptable behavior.
Parents brag about boys taking risk, but never about girls.
To paraphrase real world office debates, basically man dying after they did dangerous "at least knew what he did it for" while woman "stupid did not knew the risk". Judgement without knowing details in both cases. I havent seen dumb female death framed in terms of bravery, but I have seen dum male death framed that way. (This difference likely hurts men more then women imo, most paid jobs are actually safe)
Imo, neither that man nor that women meant to be death.
