Confession: we love "Harry Potter" here at JONJ. We devoured Books 1 through 6, waited impatiently for 7, and then engulfed ourselves, for sadly the last time, in the world of magic and wonder. Yes, we're no longer teenagers. Yes, we have significant others. And mortgages. Stupid confession.
So, are there any Jewish characters in "Harry Potter"? For J.K. Rowling certainly makes sure to include different ethnic groups, from Indians to blacks. But Jews? Surely, there must be a Moishe or Schlomo among Harry's friends.
Sadly, no. There's only background character Anthony Goldstein, who is about as interesting as a Crumple-Horned Snorkack. So we'll pass.
However... there are theories out there that Severus Snape is a Jewish stereotype: hooked nose, greasy dark hair, probing black eyes, mysterious and untrustworthy. But we're not buying it.
If anything, Snape is the stereotype of a horrible teacher. And if you find something Jewish in his description, you're either overanalyzing, or have to modify your views of Jews, or both.
And then again, seeing how Book 7 ends, we wouldn't mind that much to have him...
