How do people in this day in age become nazis/neonazies sexist or even incels when there is so much knowledge against it? Do they get anything out of being that way?
In modern times? IDK, but historically female leaders tended to engage in more war as a way to legitimize their rule, whether instigator or not. Kosem Sultan, Queen Isabella of Spain, and Catherine de' Medici to name a few, but to quote a Quartz article:
"In fact, between 1480 and 1913, Europe’s queens were 27% more likely than its kings to wage war, according to a National Bureau of Economics ... And like Isabella, queens were also more likely to amass new territory during their reigns, found the paper’s authors, economists Oeindrila Dube and S.P. Harish."
