re:"MY GOVERNMENT NOT ONLY ADDS FLOURIDE ... Nova Scotia gets KMNO4 added to their water supply
KMNO4 you say?
It has a lot of purposes. apparently 8mg in a bottle of redwine is a recipe for murder and my government puts it into my water supply???"
Remember THE DOSE MAKES THE POISON!
Your fear that ANY concentration of potassium permanganate is harmful to humans is an extension of the Linear No Threshold hypothesis popularized by Linus Pauling et al which has nearly destroyed the Nuclear Power industry and is well on destroying the rest of industrial civilization with the politicians, well meaning dupes and trial lawyers of the world.
