It means stupid people are trying to draw a difference between any actual cause of death and whether covid had any influence on said death. The poster above who brought up HIV/AIDS nailed it perfectly. Basically, people with AIDS don't die from AIDS as much as they die from tons of other maladies that feast upon their weakened immune system, Pneumonia, etc. Everyone knows they died of complications surrounding AIDS.
So these fucks are saying that many of these people didn't actually die of Covid, they died of Pneumonia. They didn't die from Covid, they died from organ failure. Etc. Therefore it isn't covid.
I didn't die because I got hit by a bus, I died from blunt force trauma to my cranium. See where I'm going here? It's just another tactic for stupid people to deny the severity of Covid to make their little brains seem safe.
