Rape has nothing to do with sexual attraction. It is all about violence.
I know that is an accepted truism. I am not a psychologist or a health care related individual. I still believe there is a sex drive in these people, and at least some of them are doing something that satisfied their sexual urges.
Are they incorporating divergent practices bearing only a narrow or massive divergence from the norm? Yes, I believe they are. As anger enters into it, I think your classification becomes more prominent.
There are mental issues involved too. These become psychotic at some point.
I’m not trying to minimize the problem, explain it away as something less than what it is by design, or dismiss anything that is vile and unacceptable here.
This is an explanation of my own views. I’m not saying anyone else should buy into them.
