If people want to engage in calling you names for hating jews then just call them names back for loving jews. They'll have no answer to it.
Turn "philosemite" and "philosemitic" in to slurs and insults (Philosemitism refers to the defense, love, or admiration of Jews and Judaism.)
The label comes from the League of Anti-semitism formed in Germany in 1879 by Willhiem Marr aka The Father of Anti-semitism, author of "The Victory of Judaism over Germanism" (1879).
Tell them that instead.
