If it were just a matter of shifting the cause of death, then total deaths would be unchanged.
Total deaths were up 523,000 in 2020 over 2019. That’s an over 18% increase year over year. Normal year over year increases are 0.3% - 0.7%. Deaths in all the big cause groups (e.g. heart disease, cancer, etc.) were normal or just slightly above normal.
And it’s only an assumption they are all due to COVID as a direct result of getting sick with it.
It’s dishonest to present the excess deaths as all directly COVID caused.
