Fuck off. A lot of people got sick because others were idiots, not because they behaved wrong. Masks are most effective when the sick person wears them, which you can't influence, way too many idiots got out even thought they felt sick and not every place in the world encouraged the use of the really effective FFP2/KN95 Masks. A lot of long-covid sufferers also got sick early on, before we even learned what they best measures would be to protect ourselves and others and before we had the vaccines that reduce the risk of suffering from it.
