All of the data claiming "schools aren't superspreaders" is from BEFORE KIDS CAME BACK TO SCHOOL in this country. It's from studies of school sicknesses in August and September.
Or it's from schools overseas, where 100% of the kids wore a mask and distance 100% of the time, which we all KNOW doesn't happen here.
Since those studies have come out, Sweden (which was one of the leaders in "kids stay in school" has had huge spikes in COVID cases. So have other countries which kept their kids in school. High school football games have absolutely been counted as super-spreader events, and That. Is. School.
Since schools opened back up, our curve has turned into a nearly vertical line in this country. This is a fact. This may be (likely is) coincidental, but the fact is, many of us can name dozens of programs, both band and football, in our own and in surrounding districts where a kid got it, then half their team/group had to quarantine, then more kids got it, and then half the season is gone. Or there have been multiple somehow unrelated exposures where multiple kids at the same school get it.
And if online teaching isn't the "best education possible" then why is it good enough for many of us to obtain masters and doctorate degrees through hundreds of colleges and universities? If it's good enough there, why isn't it good enough here?
The answer, of course, is that kids aren't adults and can't self-monitor the way they need to - which brings us to your whole issue about abuse. Parents have largely abdicated their role in educating and caring for their children in this country. If parents want the best for their kids, they need to be involved in their lives and help them, not just turn them loose. Teachers shouldn't be the first line of defense against abuse - parents should be. And let's not "what if the parents are abusing the kids" because we can what-if all day long.
