The ethnic cleansing of Palestine has forced the conversation about 'antisemitism' so that the word has genuinely shifted meaning.
"Classical" antisemitism is a narrative and conspiracy theory. Super powerful shadowy Jews who control finance and whatever else are undermining the white race and seeking to replace us through evil plans like mass migration of non-whites. The "Jews will not replace us" chant in Charlottesville is this belief. Aka Replacement Theory.
"Israeli" antisemitism is that political opposition to the actions of the state of Israel are antisemitism.
These are now totally divorced from one another. And because uncritical support for Israel overrides all other priorities, the ADL and Netanyahu are now full on supporting Musk because he's pro-Israeli.
And no, it's not a contradiction. White nationalists who want all non-whites expelled from the country or killed think Israel is great because that's where you put all the Jews.
