Just for those keeping score at home:

In post #378 , JoeyBike asks "Is anyone here claiming that helmets don't mitigate injury?:

In post #386 , njkayaker replies "People do make such claims in these threads regularly."

In post #397 I wrote "I'm still looking for you to back up your claim that some people here have stated that helmets cannot prevent injury."

And then in #411 , nj replies with "I made no such claim!"

Mconlonx is right, again: trying to engage njkayaker in conversion is a complete waste of time.
