Yeah, I thought that was it. The definition is clear that criticism of the Israeli government that's comparable to criticisms aimed at other governments isn't antisemitism. You should be able to criticise Israel in the same terms you criticise (e.g.) Russia and China, or for that matter America and the UK. But if you exclusively criticise Israel in virulent terms, or say that Israel is some sort of uniquely evil entity comparable to the Nazis, or imply that all Jews worldwide are agents of the Israeli state, or say Israel as a nation state should be wiped off the map—that's antisemitic.
This should all be pretty uncontroversial.
So your position (besides implying that I'm a cheerleader for Netanyahu) is that a good working definition of antisemitism is bad because people misuse it? What's your take on how to counter the very real antisemitism that exists in parts of the anti-Israel movement? Also, I'm sorry, but your quotation is obviously bullshit:
China is a democratic nation now? Saudi Arabia is a democratic nation? Come on. It's obvious what that means, and it should be obvious why holding Israel to a uniquely high standard among democratic nations, as the definition says, is antisemitic.
