A sex police for adults with "mental retardation"? Comment on Spiecker and Steutel.

This article is a rebuttal of the claim by Spiecker and Steutel that sex between people with mild and moderate "mental retardation" is morally permissable only with the substitutive consent of caregivers. After a review of historical, empirical and practical considerations, an ethical analysis is undertaken which concludes that Spiecker and Steutel's arguments are deeply flawed and their proposed policy morally objectionable.
