Deregulation Bill

Surely one of the cornerstones of British law is that everybody is equal in the face of it. Either people should have to wear helmets for safety reasons or they should not. If a Sikh can give up their decision to wear a safety helmet on religious grounds, why cannot other workers decide not to wear them on grounds that they choose for themselves? Why should we have different laws for different people in this country? Many people find that troubling and offensive.
