This is a spin off from the somewhat unpleasant “How Is A ‘Wet Wily’ So Different From Rape?” thread.
In that thread we started to examine and define the constituent acts which went to make up the immoral act commonly known as rape. Here I wish to avoid considering any single legal definition as that would differ from location to location and also may not include rape acts that are by their essence unprosecutable.
I had come to the conclusion that one necessary factor in rape is what we called nonconsensual domination. Where the perpetrator causes the victim to do things through threat or actual violence, that the victim would otherwise not do.
It is also clear that this nonconsensual domination is not the only necessary factor in rape, as some forms of nonconsensual domination (such as involved in parent/child relationships as pointed out by Svt4Him ) are clearly neither rape, nor even immoral.
I hope here to explore further the concept of nonconsensual domination as to when it should be considered a crime. And also the other factors that make rape the act that it is.
