When I think of Chivalry, I think of the actual definition of the word: the system, spirit, or customs of medieval knighthood. It's an ideology and set of behaviors that was created in the 14th century. And like most of the thinking that existed in the 1300s, it not something that works in modern day society. In fact, the core theories of chivalry don't really exist anymore. It mutated over the course of time from the definition of knighthood to the definition of gentlemanly behavior.
One of the most cherished examples of chivalry these days is the movie Gone With The Wind. Personally, I didn't like the movie. But as a movie buff, I understand it's importance. Still when talking about chivalry, women hold up that movie and say that chivalry is dead. I'm a guy, so take this with the appropriate grain of salt. Personally, I don't think chivalry is dead. However, it has changed.
Remember, the basic concept behind chivalry is the idea that it is the job of any honorable man to protect the women around him since they weren't capable of protecting themselves. They couldn't pull out the heavy oak chairs. They couldn't open the heavy wooden (or metal) doors. Now, it's been 72 years since GWTW was made. It's been even longer since the Civil War era during which the events of the movie takes place. And a great deal of things have happened in that time.
Things like women's rights, women's liberation due to the lack of labor because of that small blip called WWII, the sexual revolution, and the establishment of sexual harassment laws (including precedents for class action suits). These things have fundamentally altered how men & women relate to each other. Those alterations led to the blurring of gender roles. This forced chivalry to be less overt and "go underground" for lack of a better term.
As a guy, I do find it interesting that a lot of the women I know (and several I read about) pine for that lost era when men were expected to do everything, and women just took care of the home and the kids with no other responsibilities being socially acceptable. In a society where they have the right and duty to take care of themselves, women want to go back to when they didn't. The sentiment is so prevalent that there was even a movie based on the concept: Kate & Leopold.
Now, I grant you that men (for justifiable reasons or not) have become less overt in their romantic gestures. That is a given. But I ask this question of you ladies: Would you really trade in all the freedoms you have in modern day for chivalry of the type seen in GWTW or K&L? Really?
