That guy was being highly aggressive. A man would have interpreted such a blunt charge as a test, to be met and bested, not internalized. While I absolutely agree that men need to relate to women differently than to other men, in a business or professional situation or social situations that occur in relation to those, men could respond in a male fashion. She should have thrown that bag of feces back at him, for example by asking him all about his experience with the escort business. Her anger means that he got under her skin, knocked her off balance, which is a win in a male-male contest. The danger is that women will and often do sink into a defensive stance which is inappropriate…until it is needed. Think of it as a martial art.
