I had a fairly serious concussion from catching an edge snowboarding at 30-40mph, and you would be hard pressed to argue that the helmet didn't reduce the force of the impact. After being a ski patroler for 3 years, I can also say that there is a huge reduction in the number of head injuries in people wearing helmets.
I don't know why people get so antihelmet, but when it comes to head injuries every little margin of safety is important, it could be the margin between a life-altering traumatic injury and being dizzy and having a headache for a couple days. I don't care if people wear a helmet or not, but to say they don't reduce the risk of serious injury is silly.
