I got a funny joke, wanna hear it? What does a cannibal call a gas chamber? A gas cooker
Why would you joke about cannabalism? Are you really doing this?
I like to have a laugh at those who eat humans. Don't you agree that my joke is creative?
Cannabalism has real victims and your joke about gas chambers and cannibals marginalizes those people that bear the brunt of that violence. Don't continue with humor like this that is in poor taste.
I don't see why that is a problem. I'm only joking.
Victims of cannibalism suffer a great deal. They are probably tortured to death. Have some common decency so there won't be anything to make light of their actions.
