UN Chief: Gender Inequality Biggest Human Rights Challenge Associated Press UNITED NATIONS - Calling himself "a proud feminist," U.N. Secretary-General Antonio Guterres lashed out at men who abuse power and declared before Sunday's observances of International Women's Day that the fight for gender equality is "the biggest human rights challenge we face." Twenty-five years after 189 countries adopted a 150-page road map for achieving equality for women, a new report by UN Women says the reality is that millions of women still face poverty, discrimination and violence. It notes more than 70% of lawmakers and parliamentarians and managers are men and nearly 500,000 women and girls older than age 15 are illiterate. .
