Antisemitism is a form of bigotry, no more or less special than other forms of bigotry and racism.
If you read any significant amount of history you'd know that already, and you wouldn't need to prove that Antisemitism is real. Of course it is. So is anti-[insert religious or ethnic group]
Them turning any criticism of Israels actions into antisemitism is making the word worthless, it's almost a badge of honor at this point. And ironically their genocide is creating real antisemitism.
Well, it seems that at least in the case of Palestine, antisemites haven't been able to stop the ICC from addressing the real apartheid, war crimes, and even genocide that Israel is currently conducting in Gaza.
