Really? I am not the one whose posts are based on simple failures of reason and logic.
I worked for years in the desert removing toxic quantities of fluoride from well water for private well owners with solar distillers.
That's nice. Completely irrelevant to the topic of fluoridation of municipal water supplies, but nice.
I got variances for dual system use of over mineralized water from those wells.
Lovely. I am sure your parents would be proud of you. But that STILL has nothing to do with the topic at hand.
Fluoride is a toxic material in very low concentrations.
Yes. And it is non-toxic at even lower concentrations. Just like EVERYTHING ELSE.
Perhaps you should ask yourself why the germs that cause caries are dying and the teeth are surviving...
OK, so you don't know the mechanism by which fluoride reduces caries, and think it is to do with killing bacteria. Well, I guess that explains why you are so convinced of your completely false beliefs on the topic. FYI, fluoride works by preventing (and in some cases reversing) the demineralisation of tooth enamel. It doesn't kill mouth bacteria at the concentrations used.
also if it doesn't have other effects on bone and if it causes tooth mottling in concentrations less than 1.5 mg/L.
Why would we care what happens at more than twice the recommended level? It's completely irrelevant
You really need to study fluoride before you talk about it.
That's good advice, and you should listen to it.
Being old doesn't make you knowledgeable; having tangential experience of a chemical in a completely different context doesn't make you knowledgeable.
Even deriding the knowledge of people who you don't know jack-shit about, doesn't make you knowledgeable. Knowing stuff makes you knowledgeable. You should give it a try.
Bilby:
You sure are one rude person.
Not really. Unless you consider people pointing out the deep flaws in poorly evidenced, fallacy and falsehood ridden arguments to be 'rude', in which case, the world needs more rude people.
That's true; were you under the impression that somebody thought you did owe me something?
You seem to speak with the authority of a living God.
Well it's very kind of you to say so, but humility requires that I point out that this isn't actually the case - I am just somebody who happens to know what he is talking about. That's not a trait limited to Gods; Indeed, you could achieve the same status yourself, if you bothered to learn.
Sorry I just don't believe you are anything but a troll.
Your beliefs are of no consequence. Do you accuse anyone who corrects your errors of being a troll? If so, it is no wonder that you have learned so little.
My experience was directly in treating water for human consumption..exactly the same context.
Except you were taking fluoride OUT of a supply that had too much, which is the exact opposite of adding the right amount to a supply that has too little; And you appear to think that toxicity is a property of a given compound, and unrelated to dose - which is simply fundamentally wrong.
Try not be act like such a smart ass.
Try not to be so fundamentally wrong about stuff then. If your knowledge is erroneous, and/or your reasoning flawed - as it is in this case - you can't expect not to be called on it.
Experience makes you knowledgable and that I have.
No, learning makes you knowledgeable. Experience just makes you old. You can do both at once, but it doesn't always happen that way.
What is your claim to fame...being an Aussie?
Well, it is a great source of pride to me, but there are over 24 million of us now, so it doesn't really make me famous.

.
I don't have any claim to fame. I know stuff, but it's all in the public domain, so there is nothing (other than the false belief that you already know it) to stop you, or anybody else, from doing the same.
Calling someone a crazy doesn't exactly qualify you for any special consideration.
Who called anyone crazy? I pointed out that your statements are false, and that your logic and reasoning is poor. That doesn't make you crazy - just misinformed and bad at reasoning.
I happen to have a number of books on the toxic qualities of fluoride and was involved in a water district study on the effects of fluoride on teeth.
I have books on the Loch Ness monster. But having books doesn't make you knowledgeable. Learning makes you knowledgeable. You can learn from books, but it isn't automatic; and it requires the application of reason and logic to filter out the dross from the facts.
In case you don't know natural sources of water can contain fluoride.
No shit, Sherlock.
The town I lived near had a variance for fluoride up to 2 mg/L and the water disctrict tried to resist reducing the level.
Which has, once again, NOTHING to do with whether adding fluoride to water which contains less than the recommended 0.7mg/L is or is not a good thing. You really need to learn to think in straight lines, and stop bringing in complete irrelevancies as though they had something to do with the point.
They finally were forced to do so.
Good. Still irrelevant to the topic being discussed, though.
Where I lived east of that town fluoride levels in well water ran between 8 and 21 mg/L.
That's quite a lot. They should reduce that to around 0.7mg/L, if possible.
I did a lot of water testing and saw a lot of bad teeth.
I am not at all surprised. That has fuck all to do with the question of whether fluoride should be added to water supplies that don't have enough, though.
I also sold a number of solar water distillers.
Good for you. Still, if you will excuse my French, that has fuck 'tout' to do with the topic under discussion.
Fluoride is Fluoride whether it is added or naturally occurring.
Yes. And the dose is the critical factor. Too much OR TOO LITTLE is not ideal. Chemical compounds are not 'good' or 'bad'; their merit or harm depends on how much we are exposed to.
Why don't you bugger off?
Because you won't stop saying things that are wrong, and so I feel the need to correct you to avoid your anti-knowledge infecting innocent third parties. It is a little public service I try to provide.
