Basic Trope: A work or part of a work seems laden with Values Dissonance to modern readers, but it made perfect sense (or was even a bit radical) in the time and place it was written in.
Straight: A set of laws gives its women certain rights (such as initiating divorce, partial inheritance, prohibiting the killing of a baby girl just because it's a girl, etc.) but not all the same rights or treatment as men.
Exaggerated: The work specifically mentions things (such as how women are to behave, how men are the head of the family, etc.) that sound very backwards to modern readers used to gender equality.
Downplayed: Family politics in the story shows that the father commonly has the highest rank in the family, rather than the mother.
Justified: Some changes were needed, but people are slow to affect change. Giving women some rights is better than giving them no rights at all.
Inverted: The laws in question give women the same rights and responsibilities as men, and thus make perfect sense in the modern age, but did not when the work was written.
Subverted: The work sounds like it was written in The Dung Ages or even belongs in a historical Dork Age.
Double Subverted: But it was, in fact, really radical and controversial for its time.
Parodied: The work ends up being a, not entirely accidental, Unintentional Period Piece with how society works, including people reacting, in story, to things the way society at the time would have.
Zig Zagged: ???
Averted: The work makes perfect sense to modern readers.
Enforced: A period drama deliberately invokes this values dissonance in its characters for authenticity, but goes as far as possible to the fair side as to not completely alienate the audience.
Lampshaded: "Do times not change, and attitudes not adjust? Why, we've just given women more freedom than they have had before, and maybe one day they will have even more freedom than that, and this freedom will seem small."
"This site may seem oppressive, what with requiring editors to sign their edits with a screen name, but compared to similar sites of the time that required e-mail addresses, it was very much Fair for Its Day."
