Holocaust jokes actually fall into safe edgy category in Turkey. Probably because countries that weren't directly affected by WW2 usually tend to be less sensitive about it. No one actually approves of le genocide but no one gives a shit about dark humor on it either. Common example:
One day, Hitler and an English journalist were sitting down and chatting. The journalist asks Hitler:
"Sir, what do you plan to do from now on?"
Hitler then responds by saying, "I'm going to kill one million jews and one bicycle mechanic."
The journalist is then surprised and asks, "Uh, why the bicycle mechanic sir?"
Hitler then turns towards the English man and states:
"See, I told you no one would care about the jews!"
