In my post, I essentially stated "there are many opinions on how safe helmets truly are," and you reply by calling me uninformed. Are you just so anti-helmet that you aren't actually reading what people are saying?
I can't speak to what you believe you said. I have no personal beef with you-- only with erroneous information, which is much of what passes for facts about bicycle helmets these days.
One of the things you actually said was "helmets don't cause accidents", but the data suggest that paradoxically, they do. Or to be more specific, the presence of bicycle helmets has some accident-promoting effect that more or less completely offsets their injury-reducing properties.
There are some unscientific and plainly contrived studies, such as the one by Thompson, Rivara & Thompson that claims 85% reduction in head injuries from cycle helmets. If you look deeper into this study, you find that it was a very small self-selected group of children, and that by applying the same methods TR&T did, you can make their same data "prove" that helmets reduce leg injuries by something like 75% too. Yet this single bunk study is quoted more often than any other to support bicycle helmet laws and other such programs, just because the so-called results say what helmet promoters want them to say.
I'm not anti-helmet. Helmets have an important place in activities that present a high risk of head impact. I am anti-bicycle-helmet because I have done my research and discovered that not only are cycle helmets pretty ineffective, but marginalizing cycling (which is a safe activity, judged by the numbers) by getting a lot of people to believe that a helmet is necessary to do it, makes cycling more dangerous in the real world. It also makes cycling seem like a less legitimate transportation choice than it is.
Having had a look at many of the MBs in this little community here, I think it would be completely appropriate for many of us here to wear motorcycle helmets. The speed capabilities, marginal braking, improvised mechanical systems, and iffy construction of many MBs make them inherently more accident-prone than normal bicycles or MBs that fit within the normal bicycle performance envelope. But those helmets should be quality motorcycle helmets because the implied risks are motorcycle-like.
