I'm glad she could deal with that, but that doesn't mean it's okay to assume everyone else is as resilient. You know as well as I do that there are victims who won't find humor in it, and are entirely justified in feeling that way. And if you're wondering... yes, I do know rape (and sexual assault) victims. They don't find these jokes funny at all.
I'm thick-skinned, but here's the simple reality: if you respect rape victims (and you aren't the victim), you don't make rape jokes. It's just a matter of being considerate of other people. It's no different than avoiding jokes about dead children when you're talking to grieving parents.
And I know you had another reply, but I feel like I'm getting into the weeds. I really just want to focus on "not being an insensitive jerk" as a good reason to avoid rape jokes.
