I love helmet debates.
First off, I live in a helmet state, where lids are mandatory. 15 miles south, they aren't. I don't much care for governmental controls like helmet laws or required seat belt/restraint use in cars but I'd wear my seatbelt anyway, just like I always wear a helmet. I prefer to have a choice. In today's society, too many choices are being taken away under the guise protecting yourself from yourself.
The no helmet/tiny helmet is certainly a HD perpetuated thing, like loud exhaust, it's a libido / testosterone thing. You have a small member and you need to impress, so you make noise and let the bugs permeate your forehead. That ain't me, well, maybe the member thing.....

but my melon is important to me and oblique contact with asphalt and / or concrete is detrimental to my melon, much more so than other extremities. A broken melon usually can't be repaired and if it can, the results are not usually gratifying, in other words you become a veg.
Now, I'm a member of Michigan ABATE, an organization that actively campaigns against mandatory helmet use here in Michigan and while I support that, I always wear a helmet to any function they have because of the melon thing. I look at all those naked melons at the ABATE rallies and I picture a ripe canalope smashed on blistering hot pavement. Good for the flies, bad for the family, and you.
Look at it this way. If I busted my melon, Flipmeisters would cease to exist because without a functioning melon, I can't do ****.
Having said all that, I always wear a full face bucket and I don't pinch pennies on a lid because that one-in-a-million shot can bust your melon.
Besides, wearing a helmet in a non-helmet state, sets you apart, just like riding a Rocket. It's a good thing to be different. That's why we don't ride potato bikes, because we want to be......different.
Helmet threads are like oil threads. Everyone has an opinionand some opinions don't read well. What's good for me, might not be good for you but I'm me.
