On her third trip to the museum, Barton took her undergraduate students, who found the visit unsettling. Several in the group were former fundamentalists who had since rejected that worldview. Several others were gay. In part because of these backgrounds, Barton said, the students were on edge at the museum. Particularly nerve-wracking were signs warning that guests could be asked to leave the premises at any time. The group’s reservation confirmation also noted that museum staff reserved the right to kick the group off the property if they were not honest about the “purpose of [the] visit.”

Because of these messages, Barton said, the students felt they might accidentally reveal themselves as nonbelievers and be asked to leave. This pressure is a form of “compulsory Christianity” that is common in a region known for its fundamentalism, Barton said. People who don’t ascribe to fundamentalism often report the need to hide their thoughts for fear of being judged or snubbed.
