That person makes good points, though I think there is a little hyperbole at times. For one, the IFR is most likely under 1%. But even if it is 0.3%, that would be 1 million dead Americans if everybody caught the virus. Secondly, it is hard to know at this point whether some of the damage to the body is permanent. The idea that it could be permanent though should be enough for everyone to respect this and take it seriously.
