In time, you may understand.
You are saying a teacher is "much much MUCH more likely" to catch the virus after 30 minutes in the grocery store than 8 hours in a classroom with 30 kids. You are also saying the are more likely to get it from an adult teacher in the school they encounter when, at lunch hour in the teacher's lounge, than that classroom.
As I said, if you think that is the case because an adult is more likely to transmit the virus, you are the one with the misunderstanding. If there is some other reason why you think the above is true, then post it.
Just to sum up - is it your position that no schools in the US should open?
There is no need for your summation, kiidcarter8, because my position on this has been stated and restated several times now.
This country, despite having over four months to deal with it, is currently hosting multiple global epicenters of the Coronavirus. We do not have transmission under control. Therefore it is necessary to limit and monitor any interactions where that virus may be further transmitted. An interior space in typically older buildings with poor ventilation where social distancing is impossible, where implements are shared frequently, and where (in the case of young kids) mask use is unlikely to be consistent is definitely one of those places.
Therefore, on school openings, science and the experts should be our guide, not politics. And anyone who is saying "Schools are safe because the kids die at a less frequent rate than adults" is ignoring the science, very likely for political considerations.
If any of that is unclear to you, well, maybe you will get it over time.
