Here's how.
If the CDC says 40,000 people died from Covid, and somebody else says only 500 people died from Covid, who are you going to believe?
What you do is look through the rest of the CDC info until you find where they say that only 500 people died from Covid. Then you know that the CDC is lying about something.
The thing about it is that the CDC is never that straight forward. You might be able to find CDC statistics for the flu, pneumonia, the common cold, heart attack, cancer, Covid, and a bunch of other things. Then when you add them all up, you find that it's way more than the official number that died. Or you might find that Covid deaths are nothing compared with the millions that die from cancer, heart disease, and diabetes. So why do we have a Covid pandemic?
The CDC has just told you by their figures that Covid is essentially nothing, and that there is no reason for a pandemic. So, what's the real reason for the pandemic? And when are you going to start believing the other people who have already run the numbers and have found that the CDC is a deceptive liar?
