...depicting Israel as worse than the Nazis

Which of course he didn't do.   Couldn't we avoid this kind of distortion?

The repeated assertion that criticism of Israel is by definition a form of antisemitism is cynical and dangerous. While setting out to evoke a response "I could never be antisemitic, so I can never criticise Israel" it at the same time risks a reverse response, and in the process even sanitising the term antisemitic.

Racists have tried the same trick, suggesting for example that opposition to Apartheid were anti-white.
