With respect to anti-Semitic jokes, or indeed any other racist joke, just because the teller is of that race doesn't make it any less racist.
Equally, if a blonde tells a blonde joke, that doesn't make it less offensive to another blonde.
This is a public forum, and you can post and say what you like or who you are, but you must post as a responsible person so as not to offend others and be mindful of who the viewer (reader) is.
By the way, did you hear the one about the bloke...
Kind regards, Tangrams
