I think parents who don’t want to put their kids back in school shouldn’t. Just do homeschool. I think some of the reactions are overblown, because no one is forcing children into in-person schools. Many school systems have an online option, or there is classic homeschooling also.
I think schools should take precautions, we should not just let kids flood back into crowded schools. It is not overblown to want a plan in place to prevent the spread of covid in schools. Israel had to close schools back down because of large outbreaks, I know some schools in America have opened and then closed again.
From what I have read, the countries doing the best with schools have the children staying mainly with their class, so maybe 30 kids, and not interacting with other children in the school. Although, I was watching Japanese TV, and it looked like those kids were free to interact, but covid is very few cases in the country overall. That brings me to another point, if the local area has a lot of cases, then schools should not be open.
The best way to open schools is for everyone to mask up and distance and get the caseload down in the country so things can go back to a more normal situation. Even then the schools need to take some measures for safety.
