You know, I'm not sure that is the case anymore.
In less than a week Gary has been used and dumped by two different girls. Now Zii wants to throw a third girl at him that basically just wants him for sex.
If gender rolls were reversed, and Gary were a woman, and two men had used 'her' for sex and dumped her, and Zii brought a 3rd man over that just wanted sex, people would be shrieking about how sexist and offensive it was.
