>>The issue is personal freedom, not whether helmets save lives.<<
BINGO!
The nanny’s argument is a very dangerous non sequitur.
There is indisputable evidence that motorcycle helmets saves lives.
Therefore we will pass laws mandating helmet use on public roads.
If that leap of logic is allowed to stand then you are saying it is governments job to force citizens to always act in the safest possible manner.
No. I protest. I refuse. It is not for a bureaucrat to decide.
