Barack Obama is confused. After 49 people were murdered last week in a gay nightclub in Orlando, in the most deadly Islamist attack on U.S. soil since 9/11, the president turned his wrath on domestic opponents.

Many Republicans argue that Obama should identify the ideology that has motivated so many terrorists to kill Americans. That list would include, among others, Osama bin Laden and the 9/11 hijackers, Nidal Hasan, the Tsarnaev brothers, Syed Rizwan Farook and Tashfeen Malik, and now Omar Mateen, whom a former colleague described as driven by hatred, especially of African Americans, Jews, women, and homosexuals.
