Telling people to address males and females differently, telling males and females to behave differently, is backwards and sexist. Males can walk “like women” if they want, females can walk “like men” if they want, and anyone who would hold it against them deserves no regard. Letting gender affect introductions is just wrong. Also, it’s simply offensive to say that males should not spend time on their appearances. Everyone should pay more attention to grooming, especially males, who have centuries of permitted ugliness to make up for.
