Why do women deserve Chivalry?

Okay... Its a simple question. No im not asking to insult anyone. I just want opinions. Honest to goodness i am unlikely to respond to anyone unless they hurl insults first.

So here is the rub. In an equal society, why would women deserve chivalry, which for those that dont know, is a way of treating women with difference. Not going by the medieval definition.

noun: chivalry

the medieval knightly system with its religious, moral, and social code.
historical
knights, noblemen, and horsemen collectively.
"I fought against the cream of French chivalry"
the combination of qualities expected of an ideal knight, especially courage, honor, courtesy, justice, and a readiness to help the weak.

courteous behavior, especially that of a man toward women.
plural noun: chivalries
"their relations with women were models of chivalry and restraint"

And for the record, i practice chivalry with those that are worthy of it because i believe in respecting people in my care ESPECIALLY my wife.
