That was a refrain echoed by many American Muslims in interviews last week. They said they were scared not as much for their safety as to learn that the suspicion, ignorance and even hatred of Muslims is so widespread. This is not the trajectory toward integration and acceptance that Muslims thought they were on.

Some American Muslims said they were especially on edge as the anniversary of 9/11 approaches. The pastor of a small church in Florida has promised to burn a pile of Korans that day. Muslim leaders are telling their followers that the stunt has been widely condemned by Christian and other religious groups and should be ignored. But they said some young American Muslims were questioning how they could simply sit by and watch the promised desecration.

They liken their situation to that of other scapegoats in American history: Irish Roman Catholics before the nativist riots in the 1800s, the Japanese before they were put in internment camps during World War II.

Muslims sit in their living rooms, aghast as pundits assert over and over that Islam is not a religion at all but a political cult, that Muslims cannot be good Americans and that mosques are fronts for extremist jihadis. To address what it calls a “growing tide of fear and intolerance,” the Islamic Society of North America plans to convene a summit of Christian, Muslim and Jewish leaders in Washington on Tuesday.

Young American Muslims who are trying to figure out their place and their goals in life are particularly troubled, said Imam Abdullah T. Antepli, the Muslim chaplain at Duke University.
