Jamma, I really think we need to go back to the evidence presented further up that showed that lots of "Mr Averages" when asked what they thought of rape and whether they would do it replied with a resounding no. But, when the same men were presented with a range of scenarios that reflected the legal definition of rape or serious sexual assault (aka penetration of an orifice by something other than a penis without consent,) quite a few were prepared to say that they would engage in that kind of activity.
In short, many men who rape do not see what they do as rape, so don't see themselves as rapists by any stretch of the imagination. If they see a guy convicted of rape on the news, they may feel genuine abhorrence, because they don't see what they have done or would consider doing as anything like what he has done. They might read through some statistics on rape, but they don't see where they apply to them in any shape or form.
In a similar vein, I can think off the top of my head of 4 women I have known who have had experiences that meet the legal definition of rape. None of them define what happened to them as rape, even where they have experienced physical damage, panic attacks, PTSD and other awful things often associated with rape survival. None of the men who carried out the acts has been punished and I doubt any of them would see themselves as rapists.
I would never suggest that men are "prone" to rape unless kept in check by the law, fear of getting caught or lack of opportunity. Men who respect other people's personal and sexual boundaries and respect women as human beings of equal value to men are unlikely to rape because they don't feel entitled to possess, control or subjugate people (usually women) who they see as of less value than they are.
However, there are men who have been socialised to believe women are inferior to men, that men are entitled to the domestic, sexual and other services of women and that exerting power and control over a woman or women is an indicator of masculinity. That doesn't mean they will automatically become rapists. It does mean perhaps that they may be inclined to view forcing/coercing/cajoling/tricking/blackmailing a woman as acceptable but not necessarily as rape. It does mean they are more likely to justify or excuse such behaviour in other men, even if they don't resort to it themselves.
Just because you've been fed misogynistic bullshit all your life doesn't mean you have to accept it unquestionably. There are many men who question, who challenge who refuse to collude with sexist attitudes and activities every day. They're also the kind of guys who won't mew and cry that their feelings have been hurt because someone suggested that "ordinary guys" can also be rapists. They'll see that the greater harm is in the thousands of women, children and men who have their lives pulled apart by rape and sexual assault, who rarely see the perpetrators held accountable for what they have done.
