How do you find a good Hitler joke? Try a Jew and see what works
Do you really think these holocaust jokes are funny?
I don't feel like replying but I can explain this to you. Somehow, it's our community's 'sense of humour', if you get my drift. You see, the sort of people who tell these jokes or make bad puns tend to be holocaust survivors, or the children of survivors, and they believe they have a right to make these jokes because they're still upset about what happened, even though so far removed from the tragedy itself. Not to mention that they're less likely to be offended/pissed off than other groups of people who aren't as closely connected to the atrocity - no one's going to find anything controversial in jokes made about other genocides after all, whereas holocaust-jokes
Though your community may be fine with it, not all jewish communities share your beliefs. They may want to live on in peace and forget about the holocaust due to trauma and joking about it will keep bringing the event up.
