Earlier this month, President Obama made a remark about U.S. history that sent many members of the American far-right into a paroxysm of rage. Speaking at the annual National Prayer Breakfast, Obama said that it would be wrong to blame all Muslims or Islam itself for the cruelty and evil of ISIS, because every ideology and every religion includes people who are willing to distort their creed in order to justify oppression and brutality. “[L]est we get on our high horse and think this is unique to some other place,” Obama said of ISIS, “remember that during the Crusades and the Inquisition, people committed terrible deeds in the name of Christ. In our home country, slavery and Jim Crow all too often was justified in the name of Christ.”
