This is effective rhetoric, but it’s more than just that. Children and young adults are at virtually no risk from Covid. The flu–even the common cold–is more dangerous to them than Covid is. Forcing kids to wear masks doesn’t do the kids any good. To the contrary, it likely harms them both physically and psychologically.
What are the developmental consequences for babies who never see the facial expressions of the adults around them? Of elementary school students who have their concentration broken every twenty seconds by an urge to readjust the thing obstructing their breathing? Mask mandates force children to suffer for the benefit of the old and infirm.
