I think I've posted this before, but it's the most recent poll I can find on worldwide antisemitism. It's by the ADL, but even they will quietly admit that the percentage of people identifying as antisemitic is at its lowest level in recorded history. This is not to say there aren't some countries (Hungary) where it is most certainly increasing, but the narrative of a global antisemitic comeback is highly misleading.
