Do you know more about this? I have been considering the "black death" for a while, now. Not sure it is really what we thought it was. I also wonder if the treatments were part of the problem. Genetic changes in survivors may have been due to changes in gene frequencies following exposure to toxic "medicines" such as those containing mercury, I think.
If you think the intentional dumbing down of America's children via government indoctrination in schools was bad, just wait until people discover the harms of the CDC "vaccine schedule". Would dropping a newborn's IQ by 5-10 points on the first day of life with a bolus aluminum injection count as a national security risk? Which "military" does the CDC actually work for? How many CCP/PLA and ACP (American Communist Party) work for Pfizer and Merck?
