No, it does not stop. Ignoring the behavior may even be seen as agreement or encouragement. Students can do nothing about sexual harassment. Sexual harassment is just a natural way for men and women to express friendship and affection. There is nothing natural about degrading another person.
Harassment is offensive and often frightening.
Sexual harassment doesn't hurt anyone. Those that object have no sense of humor. It creates a climate of fear and distrust. It's about abusing one's power. No one has the right to force anyone into any situation they are not comfortable with.
