being jewish isnt that big of a part about his character, and alot of the humor of it comes from the fact hes actively trying to dj at a synagogue, hes more then just jewish and it isnt like the joke is "heh this jewish kid sucks balls at making beats" the joke is about this kid making beats for the fnaf rapper and yeah being jewish is apart of his character on tiktok but saying it feels anti-Semitic is just generalizing him
