Each individual family's risk tolerance (age, comorbidities, damage to family if things go bad) is different.  You might argue it is safe for 10%, 50%, 90% of the school families to send kids back to school (saying for them that your perceived likely health damage to them is less than your perceived marginal benefit for brick-and-mortar education over remote education), but I bet most of us want to make that decision for ourselves, given our own perceived risk and perceived positive/negative benefit.
