If men in general throughout human history...

Of course no decent and normal human being can or would condone what those types did of course, but then again, you could say that the reason you know plenty of men who are not violent sexual predators is because, whilst far from perfect and certainly in need of a lot of improvement, we have laws and morals as well as upbringing and encouragement that allows them to prevent themselves from being perpetrators of such deeds. (Even "assholes", as you claim, well, at least SOME of them, may have a tendency to have some limits, not to mention not wanting to be arrested and apprehended by police etc.)

Of course in real life though, not many victims would have it in them to exact revenge like shown in the movie.

But I was just wondering what the world would be like, and also what would be the state of cinema like as well, if men in general, much like most women, were NOT violent, abusive, criminally offensive, perpetrators of sexual crimes etc, by nature, and that throughout human history in both peaceful and not so much times, they didn't carry out acts like these (and loads of others) on a grand scale statistics wise, would we still have films like "I Spit on Your Grave" that empower women, even if violently, against men who violate them?

But then again, that would be a totally different world now, wouldn't it?

(Sadly, and unfortunately, there are a number of reasons as to why the overall vast majority of violent criminals are indeed men, keep in mind that for one, men are generally and naturally physically stronger than women and have mental tendencies to often unfairly compete and fight for power, and combined with a lot of other factors including historical and modern statistical evidence, its somewhat simple, even if not always easy to explain in a single sentence, to see why "misandry" in our world isn't taken anywhere as seriously (by CIVILIZED people mind you) than misoginy, of course there are plenty of men who suffer at the hands of other MEN as well.)
