I think his point is you can't compare the impact of the flu because 1) it hits every year (versus a quick outbreak) and 2) many people are vaccinated. Don't forget the '17 flu seasons was 65k deaths in the US. So we're at a little under 3x right now. So yes, Covid is worse, but we don't bat an eye at 65k deaths due to the flu.
Pull the flu/influenza death numbers from the CDC for the last decade. I dare you. In the last ten years we (in the US) have lost +500,000 people to the flu. For some reason the people that died from the flu must be lesser in value because nobody did anything about it. You would think that a single year of 65k deaths would be enough for everybody to wear masks the following flu season. And yet? No economic shutdowns.…
For flu you're using sophisticated statistical modelling of excess death combined with community surveillance of use of primary and secondary care. This will tend to overcount.
For covid-19 you're using "died after testing positive for covid, or with covid mentioned as the cause on the death certificate". This will tend to undercount (even when taking into account the slight overcount involved in people who die from other things after a +ve test).
