It is very funny, it is very interesting. About the first half of it first I thought it was some kind of old study; curious. Then I thought it could be all a farse - the absurd lack of information, the obscurity, and he is saying all these great things about iodin and still he keeps calling it a poison, etc.... like funny!! And then I thought - this guy has a serious case of iodophobia, but it is more like a religion than a virus.
And at the end, when he tells his motivations, I saw why, I thought how a certain encounter under certain circumstances can have such an outrageous impact on a mind - on quite an intriguing mind otherwise! As long as he holds on blindly to that dogma and he doesn't actually study Iodine he won't be able to have a clear mind, clear understanding, clear information.
My tiny thoughts...
