Don't fund sexism. Pornography, music that portrays women in a sexually degrading or violent manner and movies that glorify men as violent are sexist tools. Refuse to buy or use any of them. Quit porn for a week, and see if it changes your view. Learn to identify and oppose sexual harassment.
Sexual harassment is an attempt to hold power over another person.
Sexual harassment in the workplace or school is against the law, and it's your right to report it to a supervisor at work, administration at school, or the police. Listen to women. Learn from women. Numerically, women are more than half of the human population. Yet our sexist culture teaches us to believe that women's voices shouldn't be listened to as seriously men's.
