My friend was complaining about the weather, more specifically on how hot it was so I told him he was being insensitive. I told him that the Jews had it worse in the ovens.
Why would you make jokes about him being Jewish?
It's not a joke about being Jewish. Why the fuck would I make a joke about Jews? It is based on the Holocaust which happened because Jews were killed in mass ovens.
Whether it was a joke or not, the reference comes off as offensive towards Jewish people. The tone at which you say this is very important because it can be taken the wrong way given the context.
It's close minded to believe that every time someone says ovens, they are instantly referencing Jewish people.
You were the one that brough up Jews being hot in the oven, so I could only assume that you were referencing the Holocaust. Those kinds of jokes are very demeaning.
