As a Jew, I find it stupid. But people like stereotypes. I guess it's comforting. But the distance from this to anti-semitisim is not that far. Jews are not similar even by their religion. There are ultra -orthodox anti-zionists, there are atheists, there are north African Jews, Asian Jews, Eastern European Jews etc. all have different traditions and probably are more similar to their immediate social group than to each other. Even worse, Israelites don't like American Jews (eg loud, vulgar and obnoxious), which is probably what this stereotypical and horribly simplistic description is based on. So please, lookup racism or at least antisemitisim before writing such a piece (a 'positive' twist does not make it less of a stereotype, and those are dangerous).
