Boys who learn to think and act in non-discriminatory ways can educate their parents on behalf of their sisters, for instance. They may be less likely to perpetrate violence against girls, such as through bullying or sexual harassment, and may uphold egalitarian notions once married. Champions of positive norms, such as local leaders and religious figures, including influential women, can be powerful and convincing voices for change in these cases. Men and boys may be well positioned to persuade other men and boys to discard discriminatory ways of thinking.
