"The long and short of it is that when the next terrorist attack is carried out whether it be next week, next month or next year, the people and the organizations at the top of my suspect list will be Muslim. As the adage goes, 'Not all Muslims are terrorists but nearly all terrorists are Muslim'," – Aaron Goldstein, after the identity of the Norway terrorist was known.
Yglesias shows how this kind of characterization is as incorrect as it is inflammatory: "According to Europol's 2010 data (PDF) attacks by separatist/nationalist groups far outnumber attacks by Islamists." And as Zaid Jilani notes regarding Peter King's unflinching focus on Islamic radicalization for his scheduled hearing on Wednesday, "there have been almost twice as many terror plots from non-Muslims than Muslims in the United States since 9/11."
And the worst terror attack in Norway's history, came not from Islamists but from Christianists. At some point, one hopes, this will sink in.
