they want the guys to be guys, and they want the girls to be girls. They have no problem with the idea of common sense 'gender roles' and they love the idea of chivalry ... guys opening doors and, get this ... guys asking a girl's father permission to take her out on a date

I feel like this might not be a "return to how it used to be" so much as a result of the increasing acceptance of transgenderism. If you are free to change your gender to suit your personality, then suddenly the traditional confining roles are OK again.
