me and my whole family have a group chat on facebook, and we sometimes send pictures to each other.
the group was made by my brother-in-law and when he did his first message was ''this group is for our grandfather's progeny" which sounds weird..
so recently i've sent a picture of my grandfather with text on it saying "you are my progeny hahaha"
they all got mad at me saying "your dark humor is so bad, you're unstable! how could you make fun of our grandfather"....
I DIDN'T MAKE FUN OF HIM
should i tell them that they're stupid?
what to do?
