If we need 70% of the US population to get infected to reach herd immunity, and COVID has an infection fatality rate of .05%; this will kill about 1.2 Million people.

That's not how absence of evidence works. You're the one making the claim of herd immunity - not me. And also disrupting that claim, with:
