Did you not find it interesting that the serial rapist was an attractive young man who, apart from his obvious personality defects (!), would have had no problem with acquiring willing girlfriends - and that he chose an older, less attractive, victim and not the young girl beloved of most other rape stories on TV, books and films? Which so emphasised Miller's point that it is power that is important - and the chilling way that he talked about it 'being only sex' and that 'they'd already had sex so it wasn't anything special'. It emphasises the way in which young men particularly are manipulated by everything they see around them.
But he wasn't the only one who had suspect attitudes to women: the serial philanderer; the stalker; the 'peeping tom'; the smutty schoolboys; the hard porn watcher. No wonder Miller despaired at one point - but as Hardy pointed out, most men are not like that. Yes, very far-fetched in a small town - I hope.
