Why is dark humor not everyone's cup of tea?

"The common human nature tends to learn inappropriate things faster than appropriate things" 

Dark humor is certainly the next entry into the entertainment industry thanks to the efforts of social media in spreading the culture of internet humor.

The special quality of the newly risen internet culture is that it has a contribution from each and every part of the human society i.e. from office workers and college students to terrorists and hacking groups. Such an intermingle of ideas and thoughts necessitates conflict. 

Dark humor feeds on this conflict and it thrives to amuse people over seemingly insensitive topics. 

Some people do not take things like the 9/11 incident very lightly and do not like to see any jokes/humor on them. Same is the case with things like rape, murder, and terrorism. Such a preference is completely okay and it can be accounted for in real life.

But the problem is when the people in favor of dark humor forget that everyone else doesn't think the same way as them. Some of these people have gone on with their riskiest and most offensive jokes in public without any special build-up factor and have faced very bad consequences.(Daniel Tosh *looking at you*)

I am myself in favor of dark humor and I have realized (the hard way) that it is not healthy to assume that everyone else doesn't mind it too. The way to go about this is to be careful how one is putting their point out there. 

In the world of comedy, it is a known fact that even the most offensive jokes can be presented in a light-hearted, easy to digest manner.

Below is a very comprehensive video that did quite a good job at explaining the essence of dark humor.
