Even if the joke was on people who do think like that, the difficulty I have is that this type of humour challenges its audience to be either clever enough, or emotionally strong enough, to spot that it's not to be taken at face value. It exposes you if you're not. That's not a good thing if you happen to be a victim of rape or sexual abuse.
I expect I've spent far too much time trying to unravel and reassure someone who's since developed a paranoid illness following sexual abuse that I’m probably over sensitive; but the risk is that victims may not be at an emotionally strong enough stage of recovery to be able to see past taking what is presented at face value, or ready to move forward enough to see it.
At the other end there is also a risk that rapists and potential rapists, and victim blamers are probably not clever enough to get it, or deliberately interpret it as a green light.
So if it was intended to make people think, does this kind of humour help, or not? I think there might be kinder and more effective ways.
If it wasn't intended to make people think, and was straight up, then really I just despair.
