There are a number of reasons why we make no distinction between extremist and nonextremist Muslims. One reason is that nonextremist Muslims have not stood up to their extremist brothers. In the U.S., the one time they stood up, they were weak and insipid in their opposition. Far far worse than that, historically, in Muslim countries, nonextremist Muslims have been cowardly, have not stood up to their extremist brothers, and have done nothing while millions were tortured and murdered.
