> Without sufficient testing, hospitals get overwhelmed and death rate skyrockets. Is this "irrelevant".
It is irrelevant to the narrow question of whether the data show that Korea has reduced the fatality rate, which is the point being argued. Deaths from heart disease are irrelevant to the same discussion.
> My Gawd, you are the one who launched the massive detour on fatality rates.
It is not a detour. It is the single point being argued. You made an erroneous claim together with a statement that you intend to repeat it. I corrected that claim to prevent you from repeating it. When discussing that correction, it doesn't matter if you also made correct claims like that 2+2=4.
