Part of that may be cultural. It would not surprise me if a majority of men here (in the US), given the example of a husband or boyfriend who forces himself on his wife/girlfriend, would believe that it isn't rape. To them, rape is something that happens in a dark city alley between strangers. When it comes to that form of rape, they may be as sympathetic to the woman and as furious towards the perpetrator as you would hope. But the former is a completely different scenario to them. I do think that explaining to young men what rape encompasses would be very helpful in closing that gap in understanding.
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
