I want to add something to my previous post. I watched the video clip with BILD boss Julian Reichelt in German. He actually argues against the school closings and the lift of compulsory schooling during the early lockdowns. In his view this has violated the children's right to learn in schools and would have saved them from (parental) violence and he demands to re-open the schools without exceptions. But this is official government policy. It is not necessary to demand it.
The point is that 1) not all parents want their children conditioned and indoctrinated in government schools, 2) there might have been cases of parental violence but the violence from the government and the authorities to which many teachers in Germany belong (they are lifelong Beamte - civil servants) to enforce the 'Covid rules' is in most cases paramount, 3) they took away the option during the first lockdowns to take your child out of school for homeschooling, 4) additional to the mask mandates, social distancing and handwashing they now enforcing the test mandates (every student have to be tested every two days). If you don't want nasal swabs from the government you have to pay for spit tests (rapid tests) for each of your child yourself. But you have to do it in a certified test center (around 20,- EURs for one test).
In essence: If you don't want to send your children to a government school you are probably dangerous and the government should take appropriate actions. This is how I understand Julian Reichelt from BILD. Maybe I got him wrong.
