Chuck Norris walked into a gas chamber. The gas chamber coughed and fell dead.
How terrible! Do you find it funny the amount of people that have died in a gas chamber?
The joke doesn't make light of people dying in a gas chamber.
Even though the joke doesn't directly make fun of people who died in gas chambers, it is still a joke making light of the Holocaust. That is a serious event and if you joke about it many people will be upset. You should think of all the people who suffered during it and their families today who are suffering knowing their loved one died during it.
It's just a joke!
That may be but it is still mean and cruel. You shouldn't joke about the holocaust. Many people will not find your jokes funny as it is such a tragic event that you speak about.
