I hear lots of people say it in every day life (though not necessarily every day), with, to me at least, seemingly no racial connotations or tones of spite. The other day at school this kid was asking what month it was, he's a real dunce as you can tell(yes he was being serious, he did not know the month). He though that march was the first month of the year. I said to him: "Are you a Jew or something, how could you not know the first month of the year?" To which he replied, 'wow that's a really racist thing to say, and no I'm not Jewish." I then had to explain that Jews, or Jewish people, use a completely different calendar than gregorian, and their new year is in the equivalent of gregorian september.
So was it a 'racist' thing for me to say? I didn't mean it in a derogatory manner at all, just a pointing out of facts. I'm no anti-semite by any means. So really, is "jew' derogatory or just another way of saying jew-ish?
