The author’s name starts with a “von”.

It doesn’t. Fleischhauer is a shitty boring “ex-leftist” by which he means that he didn’t always want to put muslims in camps. One time he did the “actually Hitler was a socialist” argument and then pretended to be Jewish on Twitter. I don’t know who or what a Wiebke Hollersen is, sounds like a Swedish childrens’ book.
