Isn’t Israel quite happy to keep Israel and Judaism undifferentiated, though? They seem happy to conflate anti-zionism with anti-semitism, and even any criticism of the state of Israel, or support of Palestine as anti-semitism. With such broad and frankly ridiculous definitions, I’m not surprised to see a rise in so-called anti-semitism.
I wouldn’t be surprised if hateful people did take delight in the genocide Israel is perpetrating, but I don’t see it. And criticising genocidal actions doesn’t require hatred for the perpetrators in order to be valid. Anti-semites were clear to lambast Israel at any point in the past 100 or so years, even more so now. And so were normal people.
