It is amazing how much time has passed. It still seems not long ago, but I guess it was. Tons of people were born after it and have no clue anymore... probably why we see those horrible jokes people make about it.
Honestly…and I hate to even think this but, give it a few more decades and those jokes might become more and more common.
Think of the Titanic. Over a hundred years ago, that was seen as the most horrible disaster of the times. Thousands of lives lost, families broken, loved ones shattered, etc etc. Today in this day and age, how many jokes have we made involving that ship? There exist parody comedy films surrounding it and children’s cartoons around it.
9/11, it was horrible and I don’t see myself ever making jokes about it in the same way I do other subject matter, but, with more time, I have a feeling it’s gonna become the new Titantic.
