Uh no. Challenging a person to a duel over the "honor" or their female family member is pretty historically accurate. An action like this could render a woman unmarriable under hisotorical standards which would be a great offense and damage to a family.
If this was a noble commuting a crime against a lower class then yes it would be pretty unrealistic but between equals, especially nobility, acts like this would have been taken extremely seriously. Anything that interferes with a nobles ability to form alliances via marriage would be very akin to declaring war on that family by those responsible.
It's difficult to explain all the nuances of history so usually schools will paint with broad strokes of "man it sucked to be a woman back then due to X, Y and Z". However it doesn't paint a full picture, women may have been second class citizens for the most part but to say they had no influence or that their own families didn't care about them is woefully inaccurate and kind of stupid when thought about critically. Fully half the population of the human race is female, and they had a strong influence on history long before they gained the right to vote, even if most theses influences go unrecorded.
tis the truth!
One VERY important thing to remember is this: Women weren't
necessarily treated like crap, back then they were even treated better than some of the males. The reasons we say they were treated like crap was more of because women were viewed as too precious for certain tasks, and too precious for certain "horrors" of the world to be known, and too innocent to do the job of a MAN *cue exploding monster trucks with lightning bolts in the background* in anycase, women were treated VERY well. Men died for a woman's name alone, sometimes never having seen her face, they'd never do that for another man. Women could even be trained in the art of dueling in france (One was accounted as having been repeatedly attempting to court married women, to which men challenged her... and died in that duel, 10 have been recorded, the women's name was Julie D'Aubigny, she was also an opera singer, not a bad hobby.) so yeah, any accounts of women being treated poorly, at least when looking at nobility, is usually comparing modern standards to medieval standards. Also, fun fact of the day, marriages for love were only done for the lower class, upper class marriages were expected to be loveless, all your love went towards God, otherwise...
