They are. This "6%" nonsense is a failed understanding of what the CDC said and how a US Standard Certificate of Death gets filled out. What the CDC said was that 6% of deaths where COVID-19 was the underlying cause of death (defined as the disease or injury which initiated the chain of events leading directly to death) had nothing written in Section 32 Part II.
Part I of Section 32 is where you list the chain of events from the underlying cause of death (e.g. COVID-19, metastatic breast cancer, etc.) to the immediate cause of death (i.e. the straw that broke the camel's back, e.g. acute renal failure, hypoxemia, etc.)
Things listed in Part II may complicate survival, but they are NOT in the chain of events leading directly to death. Whether you have 0 things listed in Part II or 100 things listed there is irrelevant. Part I is what matters. If someone has diabetes and I shoot them during a robbery, the death isn't caused by diabetes. Diabetes may have complicated efforts to save their life, but they died because I shot them.
What you are effectively arguing here is that the person I shot died not BECAUSE of a gunshot, but WITH a gunshot.
It's absurd.
Hospitals get more money the more they say Covid is involved. The cancer patient had the sniffles but were Never tested for Coronavirus before they died - better call it Coronavirus.
