There's a very big difference between having a belief and wanting to impose that belief on everyone else. I would be surprised if most of us here who advocate helmets wanted to go so far as to force everyone to wear one. To be sure, there are such people, but I think they're in a small minority
Is that true of all safety equipment, or just helmets? Do you suppose release bindings have the same effect?
Question is, do you feel more secure skiing trees with a helmet on? Sure you do. People have already stated they are better protected against branches slapping them in the head. Which only proves that if you skied trees without a helmet, you'd ski them a little slower and would stay away from low branches and probably give the trunks a little more room. You would also ski a little slower and be more careful while skiing the edges of trails where the good snow is wouldn't you? Absolutely. People wouldn't think of hucking big air or slidding rails without a helmet on would they? No. Tyronne Shoelaces will vouch for that. So, helmet use does increase the big balls factor. People with helmets ski faster, and in places, and ski differently than they would without one. The false sense of security I'm talking about.
The bindings issue isn't comparable.
