Liddy made it pretty obvious he was a troll, so I guess I don't need to follow that line.

Funny things bike accidents.
I tried bike polo a couple of weeks back - what a blast! The local group are pretty casual, not like some of the videos you find on the internet. One lad didn't have a helmet for some reason (compulsory here), but that was fine, he had excellent bike control and as I said, it was pretty casual. The ball managed to go under his rear wheel - not his front, his rear and the result was a forward piroutte, right over the bars and onto his head. The graze was about an inch square so it was obvous where he hit - that's right, inside the area that would have been protected by the helmet. He lay on his back for quite a few minutes. Was obviously dazed when he stood and staggered to the side lines. Didn't ride again that afternoon. I don't actually know how he got home as I left before he did.

Very slow speed.
Not on road.
Accident that resulted in a head injury and included some brain injury.

If you're in an area where you don't need to wear a helmet, you've got a choice. Use it, but you are choosing to risk injury ... bit like riding in the first place but you're choosing to risk injury. So why get so het up about defending your choice (like Liddy the troll)? Make your choice and wear it.

Personally, I was wearing a helmet on every ride 5 years before they became compulsory here. I'm free spirited enough to think that personal choice is a good thing and that you can't legislate safety, much as they try. I'm happy to applaude that you have the choice, just don't expect me to agree that not wearing a helmet is a good idea.
