Don't bring your views on anti semitism onto this site. If something "appears...offensive", then report it, otherwise keep your personal opinions to yourself on this matter.
You know nothing about Jewish humour and your thoughts on this matter are both ignorant and misguided.
I suggest you read about this gentleman http://www.thecnj.co.uk/review/2008/091108/books091108_05.html and then read some of his jokes http://www.awordinyoureye.com/
Are you suggesting that this is anti semitic??
