Who were the best magicians in WW2? The jews, they enter through the door and leave through the chimney
Do you enjoy making jokes like these at the expense of those who died during the holocaust?
I didn't mean anything. Nevermind
During the holocaust millions of Jewish people were systematically murdered and their bodies cremated in large ovens. Jokes like these draw attention to their murders and can be a harsh reminder of those events. Anyone close to this event would be upset to hear these kind of jokes.
You are too critical.
If you don't want people to be critical of your remarks then be careful about what you joke about. Jokes like these are intended to mock and belittle the victims of a large tragedy. It's no surprise some people will be hurt by these comments as they recall painful memories about those times.
