Those are not equal options. However, is a dead kid equal to 1,000,000 kids repeating a grade, becoming more addicted to screens, less socially capable, more stratified along racial and economic lines? Is it equal to the increase in crime, suicide, and basic adult functionality that will come with it?
Again, most teachers work in an environment where they are the single adult and the students are unlikely to pass along the virus. The dangers can be mitigated for them as effectively as any other essential profession.
You seem to be focusing on the exceptionally young kids when defending your position. Not every kid in school is under 10 years old and unlikely to pass the virus along.... heck, during the spring I had 4 students that were diagnosed with it and that was with the virus at much lower levels than it currently is... the fact is, schools opening will lead to increase spread...
