Sunlight is not polarized. When you use a polarizing filter, you are polarizing the light. That’s why they call them polarizing filters.
Sunlight, reflecting off of a lake is partially polarized which is what creates the intensity.

Light arriving on Earth from natural sources, either directly from the Sun or reflected from the Moon, is unpolarized or, at most, weakly polarized.
There is some amount of polarization once it strikes the Earth, but all EMF radiation from telecommunications is polarized, like a laserbeam.

Since you don’t know enough about the polarization of light, it’s not fair to me to comment on your ignorance about man-made electromagnetic fields in the rest of what you said.
And please post something deeper than a Wikipedia article, or actually just look up anything that is opposite of your current bias.
