It is difficult to discern a serious threat to religious liberty from a room of silent, thoughtful schoolchildren.

The line argues that quiet, reflective religious activity by students—especially when it is non-disruptive and not coercive—does not plausibly endanger anyone’s freedom of conscience. Framed against Establishment Clause anxieties, it suggests that treating mere silence or private contemplation as a constitutional “threat” overstates the risk and can itself become hostile to religion. At the same time, the emphasis on “silent, thoughtful schoolchildren” implies a boundary: the concern is with coercion or state sponsorship, not with students’ personal religious expression. The quote thus encapsulates a moderationist view often associated with O’Connor: protect religious liberty by preventing government endorsement while allowing space for private, voluntary practice in public schools.
