The Spanish Flu Spike Versus COVID Spike

The New York Times took huge offense about 80% de facto immune but they were wrong and the data shows it now. I pointed out that 2018 excess deaths because every year in flu season you have excess hump of deaths was around 140,000 people which sounds a lot but it's out of 360 million so it's not so much. 2020 right up to March was remarkably low until there was a sharp peak with 180,000 how would that justify shutting everything down destroying the economy ruining the kids education? The dry tinder concept or low mortality one seasonal if you will causing a higher hit the next season is huge in this.
