Teaching evolution in a creationist culture

A Creationist culture, fueled by Biblical literalism, exists in the United States. A recent Gallup Poll found that forty-six percent of Americans believe in the Creationist view that God created humans in their present form at one time within the last 10,000 years.

How can we teach without alienating them or compromising ourselves?
