OK, I'm gonna take an unpopular stance here, folks.
Just so you know, I wear a helmet taking a crap, and own every kind of helmet from frisbee to snowboarding... I am a huge advocate. BUT... I do recognize others' rights to NOT wear a helmet and to NOT catch verbal abuse from those who ARE smart enough to wear helmets. Unless it's illegal, people have a right to be stupid. Besides, the world needs more organ donors.
But I, like some others CHOOSE to ride helmet-less in my neighborhood and in my local park.... That's my choice and MY RIGHT. And just like if I accept full responsibility for my own safety (and won't piss and moan if I do hit my head), I don't need (or want) to hear crap from anyone about it (except maybe my mother).
DO wear helmets.... it's the right thing to. But DON'T harrass people who don't.
Peace and Love to all (and Mom, I hope you're not reading this).
