I asked this Jewish girl for her number. She rolled up her sleeve.
I can't believe you made a holocaust joke! That seems really wrong to me.
I just thought the Israelis would appreciate it given the Jews' historical experience with numbers.
I think it's good to use humor to spread joy, but I'm concerned that this type of humor does the exact opposite. There's not much that most people would find humorous about millions of people being killed. Instead of making offensive jokes, perhaps try making jokes that don't make light of other peoples' suffering.
But I'm telling you I'm doing it for the Jews. How can I get you to understand?
Think of how upsetting is is for victims or their families to be reminded of a tragedy. This is something that is best not to bring up in a joke.
