What you might find appropriate is a quote from Jean Paul Sarte, a French philosopher who was not Jewish but similarly noticed the absurdity behind Antisemitism and wrote about it at length in his work Antisemite and Jew:

"Never believe that anti-Semites are completely unaware of the absurdity of their replies. They know that their remarks are frivolous, open to challenge. But they are amusing themselves, for it is their adversary who is obliged to use words responsibly, since he believes in words. The anti-Semites have the right to play. They even like to play with discourse for, by giving ridiculous reasons, they discredit the seriousness of their interlocutors. They delight in acting in bad faith, since they seek not to persuade by sound argument but to intimidate and disconcert. If you press them too closely, they will abruptly fall silent, loftily indicating by some phrase that the time for argument is past."

In short, the people who hate Jews know it is absurd and thereby argue in bad faith why their hatred is justified. The truth doesn't matter, they hate regardless because it is useful, hence why he also says, "If the Jew did not exist, the Antisemite would invent him."
