They're willing to sacrifice children and older people on the alter of the economy, to save Donald Trump. Most kids will be fine. I don't have kids, but I've heard coworkers talk about their school children enough to know that a loooot of kids have asthma, allergies, conditions that prevent them from doing gym/sports, and all types of other shyt that could make this situation very dicey.
Schools should re-open...but they should do so in a way that works for them. That may mean online classes in places like, you know, Florida. It may mean in-person learning in places like Wyoming where the virus cases are low. Having the government telling everyone to just go back to school in-person is laughable, especially coming from a "conservative" administration.
