Sexual harassment in public spaces is common among young adult women around the world, including in Indonesia. Public harassment is an experience that is open to both men and women, regardless of sexual orientation, culture or belief, and it causes them to doubt their own experiences. When observers see someone being harassed but do nothing to stop it, the abused individual is subjected to a more traumatic experience, and the harasser is given validation that their actions were appropriate.
