An instinctive, cultural, political & legal system and, ultimately, real world action - all of which with pro-female bias. Protecting or shielding women (physically, financially, psychologically) from the horrors of this world, from their own actions, choices and
consequences or
accountability for them, requiring men to behave or act in a certain way, to sacrifice themselves or their property (as opposed to things being basic decency(basic non-harm) and individualism-based), resulting in women being in all senses an
aristocracy, but without calling them as such.
