"This word is key to this book and to the entire Gazology genre: Genocide is the equivalent of water in Dune, the substance that moves the storyline along. If the Jews have committed genocide, everyone else can finally stop thinking about the genocide committed against them, can turn without guilt against the state that allowed Jews to protect themselves for the first time, and can sink with relief back into pre-Holocaust thought patterns—because by committing the ultimate evil, the Jews have finally proved that those thought patterns were correct. The accusation serves to justify violence against Israelis, including, retroactively, the violence of October 7, thus making them responsible for a war launched by Palestinians. The “Gaza genocide” may be an obvious falsehood, but it’s an irresistible story."
I'm sure there will be people who do this - think "the Jews have now committed genocide, so I get to stop caring about the Holocaust" - but the reverse reasoning is also possible - "People won't care about the Holocaust if Israel committed genocide, so Israel can't have committed genocide."
