Horseshit. Sorry, but there are times to be tactful, and times to be blunt, and this is bluntly idiotic. I got as far as 2 sentences in: > All types of man-made EMFs/EMR - in contrast to natural EMFs/EMR - are polarized. which is so unbelievably wrong, like, completely out of touch with reality levels of incorrect, that I see no value in reading further.

  Incorrect? What is incorrect? It looks like you do not know enough to comment with anything of substance.

    I have an FCC certification vouching that I know what those words mean. Your linked diatribe says, quote, "All types of man-made EMFs/EMR". All. Antennas are polarized because that's the easiest way to build them, and the polarization has nice properties. A standard incandescent lightbulb creates about 100W of unpolarized RF from around 400THz to 750THz. It is manmade, it's an RF emitter, it is not polarized, and it's something everyone older than the age of around 10 has spent their entire lives around. So either the author is completely wrong in sentence number 2, or they're implying that visible light isn't RF. Either way, they're wrong, and you can ignore the rest of their claims.

      > Your linked diatribe says, quote, "All types of man-made EMFs/EMR". All. Antennas are polarized because that's the easiest way to build them, and the polarization has nice properties. You are comparing light bulbs to wireless communications? What is your point? He says "All types of man-made EMFs/EMR", not "all types of manmade energy". It is clear he does not think that light bulbs are dangerous. So now you are just being confusing on purpose to muddy the water. But if you bother to READ the whole article you would see he agrees with you: "Natural EMR/EMFs (cosmic microwaves, infrared, visible light, ultraviolet, gamma rays) and several forms of artificially triggered electromagnetic emissions (such as from light bulbs with thermal filaments, gas discharge lamps, x-rays, lasers, etc.) are not polarized. " You know we were talking about EMFs from data communication types of man-made EMFs/EMR"s, but you are being ignorant on purpose, becasue you cannot even read anything that is new and conflicts with your ideas.

Visible light and Wi-Fi are the same physical phenomenon, just at different frequencies. > several forms of artificially triggered electromagnetic emissions (such as from light bulbs with thermal filaments, gas discharge lamps, x-rays, lasers, etc.) are not polarized. So, he contradicts himself. Also: > Natural EMR/EMFs (cosmic microwaves, infrared, visible light, ultraviolet, gamma rays) [...] are not polarized. Oh yes they absolutely can be, and frequently are. Polarized sunglasses are specifically made to block the polarized light reflecting off lakes, snow, sand, or other surfaces. Does the author consider light reflecting off a lake to be unnatural, or is it the OK kind of polarized because it's "natural"?
