Thirty children died after their school mandated they wear bulletproof vests to prevent shootings. Swimming lessons should probably have been exempted.
I'm really offended by your sick sense of humor regarding children dying.
It's a funny statement and seemingly inconsequential, I think it would make an entertaining chatbot.
These jokes have absolutely nothing to do with your sense of humor, the punchline of your offensive statement attacks a group that has little control over how they live their lives every day.  Hiding a hateful comment behind a joke only serves to cover up the underlying anger and motivating feelings are still there.
