This almost reads like parody:
But it isn't the first time that modern antisemites who incite hatred of Israel have tried to hijack the very definition of antisemitism to specifically exclude Leftist antisemitism, as this 2017 panel showed.
Besides that, there are two websites I'm aware of that purport to be against antisemitism but are in fact meant to defend modern Leftist antisemitism.
One is from Jewish Voice for Peace, called "OnAntisemitism.com," promoting a book where the only thing that all the contributors have in common is hating the Jewish state.
The other, more sophisticated effort of "HowToFightAntisemitism.com", a slick website that steals the name of Bari Weiss' excellent book - and uses the Tree of Life synagogue that inspired Weiss to write her book as its background image- to pretend that the only antisemitism that exists if from the Right.
This is a concerted, coordinated effort to redefine antisemitism in such a way as to hide half of it. Anti-Israel activists often share old-fashioned antisemitic memes amongst themselves while they pretend to only be anti-Zionist.
These panels and websites are meant to deflect the world from seeing the ugliness in the antisemitic Left.
