Chivalry isn't dead, but unfortunatly there isnt as much as their used to be. At least with guys my age around here. They have no idea what the word chivalry even means or how they should treat a lady.
Its up to people like u Minx, and everyone else who has kids, to teach them things like that. Parents sometimes dont realize the magnitude they have in a childs life. Anyways keep up the good work with your boys, it'll pay off for sure.
