something i think would make a lot of historical romance more accurate & interesting is the realization that people are less likely to totally disparage the ethical & social values of their time than they are to use those values to defend whatever it is they want to do
a woman is less likely to go "it's stupid that women are expected to be modest" than she is to go "there is nothing immodest about a woman going out without a chaperone" or even "i can go out without a chaperone because i am so modest"
people also seem less likely to see someone's shitty behavior as reflecting a shitty society than they are to view that behavior as being out of accordance with that society - e.g. a father who's excessively controlling of his daughters' marriage prospects isn't, in her mind, acting that way because he lives in a repressive patriarchal culture, but is actually outdated in his values - his cruelty is unmodern, ungentlemanly, stuck in the past, barbaric. we might think he's upholding the values of his culture perfectly, but the people around him who took issue with his behavior probably wouldn't see it that way
