I'm against having any legislation regarding training or safety equipment for bicycles.
Any legitimate training program instructing bicyclists on safe riding practices should include both rules of the road and the use of proper safety equipment. There should be no seperation.
Strapping on a helmet is such a simple thing to do, and it cannot hurt. Anyone claiming to advocate safe cycling should not dismiss the use of helmets.
There will always be accidents and injuries, training or no training, helemets or no helmets, laws or no laws. A good piece of advice to all cyclists is: Always be alert and wary of your surroundings...expect the unexepected.
