You're just being obtuse¹ now, it's such a reasonable inference given the circumstances that it's petty of you to place such a high burden of proof on the writer.
Also you're denying one other important piece of evidence in favour of rape. Why did the mother never speak about it?
If she had had a joyful affair with such high ranking member of society, wouldn't she be proud of it?
Why do I even bother...
In fact I've had a great deal of experience with a person exhibiting what seems like a similar cluster of behaviours.
Call it a kind of 'professional curiosity', which is why I kept the thread going past the point where any agreement seemed possible.
A poster here one said that "everyone thinks their experiences are normative". I suspect both of us are perhaps doing that.
I wish you well, and I don't mean to sound disparaging.
