Actually, the anti-Semites will simply say that the Jerusalem Post is lying.
It is a bit like Mitterrand being surprised at the outrage of Americans at Clinton's misbehavior. "So he cheated his wife with an intern half his age, obstructed justice, and committed perjury? What's the deal? Everybody does that!" This sort of behavior is considered the norm in France, so they think it's the norm in America too.
Similarly, lying is the norm for leftists--that's why they automatically assume that all conservatives lie as well.
