I would expect that the biological children of rapists raised without trauma or abuse would be less likely to rape than the biological children of non-rapists raised in an atmosphere of sexual abuse and humiliation. I wonder if this is born out in any studies.
However, if you want me to give you an exact number on how much more significant I think the social aspect is than the genetic, I can't.
I was just piping up because I thought you were saying that power wasn't a significant issue in rapes.
I've always understood the power and the humiliation of others to be a major part of the attraction.
