Have you even seen video of a blind girl getting raped in public? She didn't see me cumming either.
Oh my gosh! What do you mean she didn't see you either?
Do you know that it's possible for her to see even though she is blind? And did you know that rape isn't only about cumming?
Jokes made about rape trivializes the harm that occurs from the act. People who've experienced said act may feel uncomfortable or even become upset if they hear you making jokes about trauma they've incurred. Try thinking about what others have experienced before making such jokes.
Tell me then, has rape been a part of your life?
Rape is fun for no one. It destroys people psychology and give them flashbacks of the horrible event. Joking about it tries to normalize it like a knock knock joke and it should be serious.
