The problem is that the Israeli government itself deliberately conflates itself/Zionism with Judiasm as a whole specifically so they can screech “antisemitism!!!” at every single criticism they receive regardless of whether or not is valid.
This is not only bullshit, but also actively undermines progress against actual antisemitism elsewhere by poisoning the signal-to-noise ratio by perpetually being the Boy Who Cried Wolf.
For anyone non-Jewish looking for a scrap of perspective on the matter, remember after 9/11 when every response from every conservative about every overtly shady thing they did was to parrot, “Why do you hate America???” It’s pretty much the same idea.
