How do you get a Jewish girl's number? Check her arm.
Do you think its okay to make such a joke about Jewish people?
I think Hitler did nothing wrong.
Making jokes about the holocaust is in bad taste. The holocaust created many victims and its impact can still be felt to this day. Try being more sensitive to the ordeal they went through and how you'd feel if your family experienced such an event.
It's fine to make a joke now and then.
Joking about something so serious lessens peoples awareness of what led up to it. If we dismiss the warning signs it could happen again before people even notice.
