Germany isn't arresting parents, taking their children away, and sending them to re-education by government-approved foster families for poor test scores. They're arresting parents, taking their children away, and sending them to re-education by government-approved foster families because they're Christian. Google the Romeike family (who escaped) and the Wunderlich family (who didn't) for some examples. Also, a shorter answer to your question: Because Germany signed the UN Declaration of Human Rights. See Article 26(3).
