And just to be complete here is the graph of ONS figures comparing excess deaths vs 5 year average from 2014/15 and 2018/9 flu spike with BOTH 2020 excess deaths all causes AND deaths where covid-19 is on death certificate.
So even if you only take 'covid-19 deaths on death cert' (purple line) and assume NONE of the excess beyond that is under reported covid-19 deaths, it is still clear that this event is not similar in scale to previous flu outbreaks seen every 5 - 10 years in England and Wales. For that to be the case it requires that none of the excess deaths above those where covid-19 is on the death certificate is under reporting AND that of those where covid-19 IS on the death certificate more than 50% of those are incorrect and covid-19 was not involved in those deaths. And then you would then have to explain the 6-7k excess deaths seen in weeks 16 and 17, that you claim are not covid-19 (in order to be similar level to previous flu outbreaks) as being from delayed treatment (delayed by a matter of weeks) or people not seeking treatment leading to death in a matter of weeks or suicide or starvation. The numbers just do not add up.
But why waste your time thinking about any of that when you can just spend all your energy coming up with support for conspiracy theories that support what you thought from day one ?
