About a half dozen activists conducted a silent protest during Thursday night's Sioux County Conservatives' Pizza and Policy meeting.
The protesters were expressing their concern about the evening's presenter Stephen Kirby, a Des Moines author of five books about Islam.
Approximately 120 people attended the event at the Sioux Center Public Library.
The activists said Kirby instills fear and misinformation into the public about Islam. Kirby says his work and research is meant to give people a clearer understanding on the religion.
