Uh! I love offensive humor when its done properly!
A lot of people don't really have a great grasp of why somethings funny tho. Like they don't understand the context and think the reason people are laughing is because its just cruel. So they make cruel jokes of their own, and it never lands and all they do is make their (1) friend have to explain to their friends why you're like this and that they won't invite you along anymore.
Offensive humor only works contextually. like you can make jokes about your own plight and the things you can personally relate to. Because theres always going to be people who are in the same position as you are and will find that a witty observation.
"If the person on the gallows makes a grim joke, that's gallows humor.
If someone in the crowd makes a joke, that's part of the execution."
heres a really good twitter thread on it
