I'm afraid Judaism is more ethnically injected than anyone seems to admit, especially when you start bandying about phrases like "stereotypical Ashkenazi Jewish looks" and whatnot. Face it. People know what a Jew looks like.

And I'm gonna have to go ahead and disagree about coyly inserting Shabbat, davening, and the rest of your J-Bomb fallout into conversations like it's nothing. It really sounds obnoxious. Is it possible to do it without making it sound forced? How about when it is actually forced? I really don't know why anyone needs to be thinking this so thoroughly.
