Wondering if this would be classified as “disinformation” — “ No, solar flares do not affect human health”

This is definitely disinformation. Solar flares can and do effect human health, for instance a solar flare and resultant CME killed over 10 thousand people in Europe .

If a solar flare occurs near mid day it has a much smaller cross section of atmosphere to penetrate than say one that occurs at 9 0clock in the morning. A flare rated at X1 or higher near mid day is extremely dangerous.

"They" will tell you that radiation from the sun cannot penetrate the atmosphere and they would be lying, the reason being people would avoid bad space weather just like any other kind of bad weather and not go to work, Profitable to lie. The next time you hear someone say gamma and x rays cannot penetrate the atmosphere , ask them why they can penetrate your body but the light you can see from the sun cannot. It is plain common sense x and gamma LIGHT WAVES are more penetrating than visible light.

You'd probably be stupid for that.

This in itself is disinformation,
Give me links, Please. I've not heard of this fable.

A big enough flare will turn you into a smoking carbon meat stick, how is that for human health?
