But men (as a class) look at porn. Right? We can all agree on this?
It's like when people get upset about 'all men are potential rapists'. All it means is, under UK law, rape is unconsensual penetration. All men who have penises could do it. It's the lowest common denominator that defines people who could commit rape.
Yet some people get really upset because they think what is being said is that men must and will rape. They think you've defined what a rapist is, not given the widest group of the population from which a rapist can emerge.
I don't know what the solution to the communication issue is. If we never acknowledge the class of people who are potential rapists, we're sort of talking as if it's a perpetrator-less crime. That way you end up with people who have my dad's attitude - he thinks rape is a 'woman's issue'. I find that extremely sad, really, because the result is that he has all these (frankly) horrible and disturbing ideas about what is 'real' rape, but he would never trouble to examine them because he is so convinced that rape is only an issue for women to worry about. He would never examine his own behaviour or the behaviour of men he knows, because he's convinced that he already knows men don't rape, it's only some ill-defined subsection of people he doesn't have to think about.
I think it really matters that we name the classes of people who do things, as well as the victims. I don't have any issue with people saying 'white people enslaved black people', because that has been true at various points in human history, and it has had a significant effect on the shape of the world. I don't feel the need to say 'yes, but black people enslaved other black people too, and there are trafficked women who are white, and, and ...', because I can see that someone wants to talk about a different issue from those.
