I don’t know if he is sick. Considering most kids his age have been brainwashed with anti-Semitic/anti-Israel/pro-Palestine blather in school (Canuck schools do it too)...surprised he would visit Anne Frank House
I’d like to know who leaked his comment in the guestbook. That wasn’t very nice.
Also, if he took the tour, he will have seen the many photos of movie stars with which Anne decorated her room. I remember Ginger Rogers was one. Perhaps that’s what prompted him to write what he did.
