My wife and I have been together for nearly twenty years. In that time, we've regularly engaged in rape, dominance and bondage activities. We're still married, happy, well-adjusted people. In fact, I would say, a good deal more healthy than we were when we met. Which leads me to this point:
Kate, your insistence that porn films "encourage" these fantasies as if that's a bad thing is an attitude that's more likely to cause harm to people than the fantasies themselves ever would. People do not have any control over what turns them on, any more than they have control over what makes them laugh. What you're saying is designed to make people feel bad about themselves over something that they have no say over. You may as well denigrate people for being gay or black while you're at it. I didn't ask to be into this stuff, it just turned out that way. The same goes for my wife. We found each other, we have an outlet.
Growing up, I truly thought that there must be something terribly wrong with me. And why? Not to be overly strident about this, but basically, people like you. People who can't keep their judgments out of my fantasies. I have no problem with porn of that type because, to slightly overstate, those fantasies should be encouraged. If you can find an outlet for these activities in a safe, secure environment, have at it. Nobody's getting hurt, and everybody is enjoying themselves.
Any human being who would see these movies, then go out and rape somebody because the movie thought it was okay, was pretty damaged goods to begin with. That guy was gonna hurt somebody no matter what. Saying that Ms Gray's porn can turn an otherwise normal, healthy guy into a rapist is absurd. It's no more valid than the old bit about how heavy metal albums can make a normal teen commit suicide.
In short, get off your high horse. You're hurting people more than Ms Gray could ever dream of doing.
