One element of the liberal ideal of secularity is the principle that the state should treat religions neutrally: This is the religious neutrality requirement. Applied to religious belief systems, the principle stipulates that the state should not take a position on whether or not a certain religion is true. I challenge this ideal and argue that teachers in public schools sometimes need to take a position on religious truth claims in order to avoid the risk of promoting false beliefs. I (...) then argue that not acting to avert these implications is sufficiently costly to justify the abandonment of this requirement. (shrink)
