A British school was blasted Friday after kids as young as 11 were told to shout obscenities during a lesson in swearing. Expletives like the f-word and c-word were written on a blackboard before a teacher explained their meaning to 30 seventh graders. S.t Laurence School in Bradford on Avon, Wilts, claims it was part of a sex and relationship education program to "dispel" the myths of swear words. But parents say they were not consulted by head James Colquhoun about the class and say kids were left "deeply upset."
