He's not incorrect with what he said though. It mostly affects old and the weak and in shitty countries the old and the weak have already passed away even without covid.
From your first link:
> While people 65 years and over have accounted for 79% of the at least 223,984 COVID-19 fatalities in the U.S. recorded by the Centers for Disease Control and Prevention (CDC) (whose tally lags behind other institutions that are tracking the death toll), a number of younger people have died from the disease.
At least 410 people in the 15-24 age group have died while young adults ages 25-34 have accounted for at least 1,725 COVID-19-related deaths, according to the CDC.
And even the youngest Americans (children under 15) have not been invulnerable to the disease -- 81 died at last count, according to the CDC.
so he's right generally speaking.
