Personal Freedoms and Fluoride

To: Southampton Express and Echo:
Sir,
I wish we had David Davis and his concern for loss of fundamental freedoms speaking for me and my colleagues in the Avon, Glos and Wilts Safe Water Campaign. PM Margaret Thatcher (BSc Chemistry) wasn't too concerned about them in pushing through a Water Bill in 1985. Despite a 399 Commons abstentions vote, she 'conferred' fluoridation on the population of the emerald isle. Was she really that worried about Irish children's teeth? If not, what else did she have in mind?
