People continuously forget about (or maliciously omit) even a single step beyond someone's infection. One infected person can spread it to others. Even if the individual's risk may be low, soon, you start spreading it to people that are more at risk. Schools can thus become superspreader locations that put their parents and teachers and whatnot at risk. Whether or not everything we did with schools is right, not doing anything would've led to millions of more people dead.

Everyone certainly did some wrong things and arguably are continuing to do so, but "hysterical" is not how I would put it. We were facing a [relatively] unknown virus with poorly-understood effects to this day. We still can't predict who will be affected how by it.
I think this rhetoric is dangerous and some points of it are [to me] blindingly obviously wrong.
