The point is that the normal and decent people of the Muslim community don't seem capable of acting as a political and social counterweight to the Islamists, either due to passivity, fear, or conflicted loyalties (i.e. not wanting to betray "one of their own", no matter how terrible they acknowledge him to be). It's kind of analogous to how the normal working and middle-class blacks in America can't seem to act as a political and social counterweight to the thugs and race-victim hustlers. That's why this guy stands out.
“Nobody doubts that there are many, many Muslims who are perfectly normal and decent people.”
