"But are the measures which we are rightfully calling for from national and Community institutions any good if we politicians fail to proclaim, beforehand, that this truly basic right to human dignity is being violated by sexual exploitation, particularly prostitution?"
Or, que vaudront les mesures que nous réclamons légitimement de la part des institutions nationales ou communautaires si, en amont, les responsables politiques, dont nous sommes, ne proclament pas l' atteinte à ce droit réellement fondamental de la dignité des personnes que constituent l' exploitation sexuelle et notamment la prostitution ?
