If a student of anything walked into any place of it's relevant study, they'd be laughed clean out of the room by those who have the study and the experience. They'll also tell you that experience will often times trump and even in other situations, completely negate the study the student may have thought to be 100% factual. Since we're just throwing things out there.
I don't see how this is relevant to the discussion. He posted a bit of academic research. You've dismissed it as irrelevant to your specific point. He's indicated that it suggests a likely outcome, but admits that it doesn't actually study your exact point. You go on to suggest that if he, as a "student" were to show up someplace where "professionals" work, he'd be laughed out of the office.
First, even if that were true, it'd be irrelevant.
Second, it's not true. In every industry I've spent time in, interested students are treated with a great deal of respect and while professionals may debate with them to discover what they know and whether their passion really lies in the subject, they know that the student is the future of their field, and should already know many things the professional does not. There may be individuals within an industry that prefer to hate students, for whatever reason, and push them down, but they are clearly in the minority.
This is my experience, and I am unprepared to show a study which confirms this.
Back on topic, rape jokes are like cussing. Swearing doesn't provide any useful information to a conversation that can't be made using non swear words, and likewise the good and/or funny rape jokes don't require rape, they are merely another joke tossed on the framework that rape provides, and they can be transposed into other jokes. Rape jokes that are truly and fundamentally only about rape have no worth or value in our society.
