To be liberal "is to be elite", a university lecturer once told me.
I took it to mean only the privileged can be so inclined.
The theory resonates each time I read anti-fluoride fulminations inked emphatically - and regularly - on the opinion pages of this newspaper.
The missives also take me back to the days I ambled to school chewing fluoride tablets my mother dispensed as we walked out the door. I was one of the lucky ones. My mother's nursing background made for robust domestic health.
That's why I'm minded to agree with Children's Commissioner Russell Wills, who recently claimed the fluoride issue is less about science and more about values.
