Good for you; I must be accustomed to professionals who hold their speech, conduct and humor to a higher standard.
My apologies for interfering in your fun. Please, continue to make light of a gruesome, horrifying act that is part of a larger war that has cost countless innocents their lives. You're right; you obviously hold the intellectual and moral high ground on this issue.
Gee, sarcasm is fun
Where did it say we were having a business meeting?
And sarcasm aside, as others have mentioned, black humor is normal and common.
And I've yet to find the discussion board, where low post-count short timers chiding the rest of the board on morals or manners goes over well. Granted, you weren't the first, so perhaps you felt you had company, but part of being new is not knowing if those individuals have their own axes to grind on other matters, and were largely being dismissed out of hand.
