I suppose I confused "yew" (which I don't know what it means) with "jew". When "jew" is attached to a common word (that usually doesn't have it), in many cases the intent is antisemitic. And I suppose it's not impossible for someone to deliberately write it as "yew" instead.I am sure it is some kind of joke you don’t understand.
What I don’t understand is why you think that it was potentially antisemitic.
