Could you please cite a source that says most transmission is pre-symptomatic or asymptomatic? Is that new with the delta variant? The studies I've seen have more recently concluded that asymptomatic transmission is far lower than previously thought. Although it probably doesn't matter, since the plurality of symptomatic people below the age of 55 are going to have symptoms hard to distinguish from a cold. Regardless, you make a fair point, but for a virus to kill you, it's going to be more severe in earlier phases, and less likely to be transmitted by a person in a bed than one walking around. Sure, they might have spread while they were walking around, but the proportion of time they are infected and mobile (higher spread) is lower than if the virus is milder. Covid hawks seem to have only one answer for all news items: be more afraid, lock down more. It's tiring, and reminds me of the right-wing equivalent after 9/11: Everything was terror, or potential terror, and you need to be afraid, and if you aren't afraid, it's because you are unpatriotic, stupid, or both.
