It certainly doesn’t seem antisemitic to me, mainly for the reason mentioned by mojo pixy
It seems to me that it opposite-says Israel shouldn’t exist.
It certainly means Israel shouldn't exist in the brutally oppressive, racist state it currently exists in. But this isn't even an anti-Israel sentiment IMO, let alone anti-semitic. It imagines more than anything a changed Israel, not a non-existent one. Unfortunately too few people have the courage or imagination to try and create this change. And too many people are actively opposed to it for basically racist reasons.
Also, Israeli spokespeople more and more seem to act as if they speak for all Jews everywhere and it's a shame this so rarely gets challenged. But not a surprise because for years now anything other than the unquestioning acceptance of that pretence as if it were reality gets you if not Jewish branded anti-semitic, or if Jewish a self-hating jew.
