Their PR machine is amazing in how it's conflated criticism of the Israeli government with anti-Semitism, in a country where religion and state are supposed to be separate (not that we're very good at that, mind you). And they've convinced the world that the Holocaust somehow allows them to perpetrate the same crimes against humanity with impunity.
It's incredibly frustration because the only "reasonable" opinion allowed is full-throated support of Israel or else. There's no allowance for nuance.
