Geez. 

Didn't know you guys were the soft type. Sorry if it made you uncomfortable. I do it so often with my friends IRL that I forget not everyone understand how un-serious it is. 

To me, it's a way to mock what evil was done and remove the power it hold on modern minds. If you refuse to talk and joke about it, it means the Terror won and it leaves a permanent scar. It would be different if it was recent, but this is over 70 years ago. I do same jokes with any Historical events from Antiquity to Modernity. I guess the deeper you delve in it, the less you remember how serious it actually is/was. I heard plenty of Jews make jokes worst than this, mind you. Stating the same reason as I did. Though, that's no excuse.

Anyyyyhow, I know how to admit I was at fault when I was, and I was. Sorry. Extra sorry if anyone here has any ties to what atrocity was perpetuated back then. It will not happen again.
