From the Quartz report of the visit.

In a speech capping off his two-day visit to his father’s homeland, Obama also compared sexism in Kenya to Americans who hold on to the Confederate flag—which is frequently used as a symbol by US white supremacist groups.

“Every country and every culture has traditions that are unique and help make that country what it is, but just because something is part of your past doesn’t make it right, it doesn’t mean it defines your future,” he said.

“Around the world there is a tradition of oppressing women and treating them differently and not giving them the same opportunities, and husbands beating their wives, and children not being sent to school. Those are traditions. Treating women and girls as second-class citizens. Those are bad traditions: they need to change.”
