I think you don't need a helmet, but if people wear one I really don't care, but Like closetbiker I am against false information being spread about them.
I wore a helmet for years before I decided to remove it and I can respect anothers choice if they want to wear one.
I may have an argument with some of the reasoning people give for wearing helmets, but I wouldn't denigrate another just because I don't agree with them.
Denigrating others doesn't help people understand an issue; more often it fosters alienation, feeds ignorance, and makes things worse.
