That is a grinding damage, not blunt force. Notice the area has been shaved away, as if with a sander, rather than displaced outward/inward as an impact would cause.
whether or not the damage is actually blunt force doesnt matter as the post is implying that the helmet will protect you from blunt for of strong enough to cause a hole like that in the helmet
Not really. There is absolutely NO implication of that, anywhere here. Though, regardless of the nonexistent implication, the simple fact is the helmet offers a hell of a more protection than not having a helmet on your head.
This seems to be the same discussion as around vaccination, the thread of guns or the "believe" in global warming. I'd say we let those who ignore proven facts go their way, natural selection will do its job.
Oddly enough, skidding across pavement at 70+ mph has a very similar effect as a power sander.
When I was in high school some guys were drag racing and the winner was on a motorcycle and decided to pop a wheelie at 100+ mile per hour. Lost control and skidded, without protection. His face and part of his skull was gone by the time he stopped.

But how the hell did he do it at that odd angle? On the back, sides, or face I understand but on the top right? Either his neck was really broken (making the helmet pointless) or he was basically standing on his head.
He could have been dragged by the bike, which could easily account for the angle. He almost definitely would end up with broken bones, but not necessarily fatal.
