That’s really offensive to Jewish people, making jokes about that kinda stuff. What Hitler did was completely out of line, he gassed millions of Jews, and was a horrible person. The fact you are joking about something so serious is absolutely downright disgusting. For all you know, some people might have some family members who were gassed by Hitler. You don’t know, so you can’t just “assume” we are all fine with it. I suggest you just simply take a step back, and just have a think about if I turned the tables, you were Jewish, your great grandparents were killed by Hitler gassing them, and someone told you to get in a gas chamber. That would offend you, and is probably the same for anyone else.

What I’m saying is, just don’t joke about something like that.
