The Nazi regime started slowly, over many years. It started with demonisation of some groups, and not only Jews. Beatings, shops windows broken. They were called vermin and worse. Slowly, slowly... it took years. My mother was studying in Munich in 1932- she saw it all and had to return home early, as it was escalating.
If you turn boats away, knowing they will drown- yes, children too, like Anne... then that is the beginning. Did yout watch the Documentary about Aghanistan last night. So many children, much younger and the same age as Anne. Not just one, 1000s.
