Your comment doesn’t make any sense because how would the absence of an infection ever arrive at a debilitating outcome and thus be a point of comparison? The parent claimed COVID doesn’t cause debilitating outcomes. I provided evidence it does, including specific use of the exact term by medical researchers. When they couldn’t refute that, they made an ambiguous appeal to other infections to distract from being wrong, trying to shift attention from their original, unsupported claim to a new claim (COVID is the same as other viruses), and demanding that I provide evidence contrary to that. But that’s separate from the truth or falsity of the original claim, and thus irrelevant.
