Facts. Facts matter. "Of all the tragic facts about the history of slavery, the most astonishing to an American today is that, although slavery was a worldwide institution for thousands of years, nowhere in the world was slavery a controversial issue prior to the 18th century. People of every race and color were enslaved – and enslaved others. White people were still being bought and sold as slaves in the Ottoman Empire, decades after American blacks were freed." “You are entitled to your opinion. But you are not entitled to your own facts.” - Daniel Patrick Moynihan
