People are afraid of being antisemetic. If you just show them jewish behavior they will eventually figure out it's actually the jews. "death to jews they think you're a filthy goyim animal" doesn't work as well as "you know there are these crazy religious people out there who think they are genetically superior to everyone else and think they are just beasts to exploit." Specially if you can leave them bread crumbs where they end up going "wait, is he talking about muslims or jews? they're both actually pretty bad"
