That study was measuring masks ability to prevent being infected with the virus, not spreading it, so not directly applicable to parent's claim

I agree but the issue is no such study exists. Which is why I told them straight-up that their claim is not in good faith. Masks have never been shown to stop community transmission of respiratory viruses.

In fact if we back up for a bit and look at the immunology and population dynamics involved it's not even clear that we should want to slow the spread of SARS-2 or other respiratory viruses in the general population. We literally did a "stop, drop, and roll" of almost the entire global economy, got vaccines out in record time, and what do you know, SARS-2 is still ripping through the population just like it was always destined to.

We're fighting against quicksand.

We are fighting against quicksand, but virtually anything that slows transmission makes it easier to stay afloat. And letting it run its course is going to kill a lot of people, and the measures that were put in place almost certainly saved a lot of lives. I personally think that anything that might reasonably be used to slow transmission should be used, if for no other reason that to make sure that hospitals can keep up, and that vaccination rates can reach a point where new variants are a minor annoyance rather than a massive health crisis.

Masks haven't been shown to reduce transmission, they have abundant deleterious effects upon wearing them, and they could even worsen transmission by increasing the net release of aerosols (due to the larger net volume of air moved as a result of the user inhaling air that has relatively more CO2 and therefore relatively less O2 than a normal breath; that's without accounting for the possibility that masks actually nebulize what would have been respiratory droplets into fine aerosols as the plosive force forces the droplets through the mask fiber mesh)

So even if you don't accept that we shouldn't try to fight the inevitable (which you should accept, but I don't feel like going back and forth about it), recommending mask mandates as an intervention is a foolish strategy. They've never been shown to work in an RCT and they certainly haven't worked in real-world community settings.

I think you missed the point. It's running its course either way. We had insanely high mask compliance in america, even in red states, we've had on-and-off lockdowns for a year in blue areas, we've had widespread vaccination, and it's still spreading to and from vaccinated people no problem.

Furthermore you seem to not understand that different members of the population are at different risk levels. For example, people in their 20s can acquire the SARS-2 infection, beat it off, and have robust, enduring natural immunity, which will prevent them from subsequent infection and especially from transmitting it. Vaccination alone does not achieve that result. Thus why you're fighting against quicksand.
