As chivalry died in men, good faith died in women. It's hard to know which died first, but do not be fooled that their murderer was not the same: the printing press, and its later accomplice, the camera. The truth is that neither existed as a rule between genders. They were mere social contracts between people of the same class. No chivalry was shown by higher status men towards lower status women, nor was any good faith bestowed to lower status men by higher status women. This truth became unavoidable when people could see and read about the reality of how humans treated and exploited each other. So it became clear to everyone that we must press our natural physical and social gifts and privileges mercilessly, or be abused.
