I call it a case of unintended consequences. But absolutely yes - it simply gave antisemitics another reason to hate
my cousin has just completed a thesis exploring antisemitism in prewar Netherlands. She makes reference to to post October sentiment as well. What she highlights is what many of us know and what is glaringly obvious on hotcopper - that antisemitism is latent across the world. After millennia of persecution and discrimination and differentiation from the non Jews it has been so firmly embedded in the psyche that it needs simply a reason to emerge.
it has never taken much - famine - let’s blame the Jews, pestilence and disease - Jews must be to blame. Conflict - it is of course the Jews fault. Economic woes - it’s because the Jews control the banks, the world, the Americans.
people find it hard to differentiate social, religious and political manifestations and some - the rat and the dog being among them - seem to like to position themselves as tolerant and most definitely not antisemitic, while stepping over the line in the way they interpret events and history.
sadly Netanyahu hasn’t helped much but anyone with a broad understanding of Jewish history across the world, and capable to integrating complex and challenging run of events would be able to make better sense of current events regardless of how abhorrent they find them. Prejudice stops them having any interest at all in getting to grips with that (imo)
