“All doors open to courtesy”

Feminism from how i perceive it, for one among many things is to break the barriers of things labeled as male or female.
Today on the bus, while sitting i watched a woman or two stand right over men who didn't offer their seat. Now, one could say they are not offering their seat because wouldn't that go against the false idea that women need seats more than men? Would a woman be offended that a man offered her a seat purely based on the fact that she was female. No, i don't think so. Although some people can classify more actions under feminism than it really is supposed to stand for I think we should still consider the importance, or at least the value in chivalry. Chivalry; knightly virtues, honor, courtly love... modernized.
