Thank you--you sure get tired of it. Hers definitely wasn't a good reaction when someone points out they were offended, and made me feel more spit upon. I did talk with my other coworker just now--she is aware it's "something you don't say at work", but I really don't know how she feels about Jews and antisemitism, but she knows I was upset and she is a very decent person, so we'll see what she does with it. I don't know the offending coworker as well, so will decide if I want to take on talking with her about it later.
