Literally the article is barely about the graffiti sign, basically: “Sign graffiti bad, maybe make exhibit about anti-Semitism during the Holocaust against Palestinians! Anyways here’s this story about two probably cool dudes who fought the Nazis and opened this library. What does it have to do with the graffiti? anti-Semitism duh!”

Or maybe the graffiti artist was making a point that the Holocaust library probably will need an Exhibit on Gaza soo, too? That sure would have been a nice thing for the author to explore instead of copy and pasting an article straight from wikipedia, basically.
