I suggest using the "Chanukah" spelling instead of "Hanukkah." The usage might have a bit more sting if it was spelled the traditional Jewish way rather than the more easily pronounced version for the general public.
Don't combine it with the three parentheses. It needs to be nothing but "Happy Chanukah" so they will have no choice but to list that as "hate speech."
Most importantly, only use this when the Jew whom is being targeted is demonstrating especially egregious behavior, such as openly advocating for the extinction of whites. Overuse will lessen its effect.
Also, to anyone of Jewish faith who may be reading this: Happy Chanukah.
(Clarification on the recommendation for restraint in usage: If we deployed this in every instance where there is a Jew to be identified, we'd come across as displaying animosity towards them simply because they were Jewish, and not having an agenda outside of unwarranted bigotry. By tying this campaign to overtly anti-white sentiments expressed by Jews, we will force skeptics to realize there is a reason for our viewpoint other than simple and baseless antisemitism.)
