So I was fucking this dead whore.
Why would you have sex with a dead body?
Because I have a disease that was caused by rape.
Even though the rape involved a dead person, rape is damaging to a person and joking about it can trigger a person. Making light about it can be hurtful, just like you would be hurt if people made a joke about something that caused you pain.
Hey, I'm trying to relieve some tension here.
I just think this is really inappropriate. Can you find something else to joke about that doesn't harm victims of real crimes?
