Tom Jones, a soft-spoken man with white hair and wearing a slate-gray jacket, held up a copy of The Terrorist Next Door by the conservative author Erick Stakelbeck in the private dining room of a seafood restaurant in Kernersville, North Carolina, on a recent Thursday evening.

The presentation marked a coming-out of sorts for Jones, who had announced the event a month earlier at a regular weekly luncheon in nearby Winston-Salem that features different conservative speakers and Republican elected officials. About 20 people attended, representing professional conservative activists, GOP volunteers and militia types.

Jones’s presentation was repeatedly interrupted by comments about killing Muslims from Frank del Valle, a staunchly anticommunist Cuban immigrant, with little or no pushback from the others in the room.

“Can we not kill them all?” Del Valle asked, about 15 minutes into the presentation, during a discussion about the differences between the Sunni and Shia sects of Islam.

“The community is completely traumatized,” Abdullah Antepli, the Muslim chaplain at Duke University, said. “When they hear someone talk about killing Muslims, they know that could happen to any of their loved ones. When they hear about that meeting, it just brings up the maximum level of fear.”

Antepli said Muslims in North Carolina were talking about looking for employment in other states so they could move to areas, such as the north-east, that are perceived as more hospitable.
