I think our attitudes to rape are understandably knee-jerk. Rape is always, always wrong. All rape. Including having sex with willing underage girls.
But rapists... Let's face it. We allknow rapists. We probably just don't know who they are. People who, when younger fucked hopelessly drunk people. Or who kept putting the moves on their partner til he or she gave up protesting... And some of them went on to be better men. Good men, in fact.
It doesn't excuse what they did at all, but we can't fix someone in our minds as RAPIST and let that negate every other thing we think or feel about them. There are too many rapists. Life is too long. People do many other terrible things... Not all people, but lots.
And so with Bowie, and Peel we have men who did a terrible thing. Probably, realistically, more than once. But who, as best we know, changed and stopped doing the terrible thing and spent the rest of their lives in appropriate relationships with empowered women. Who did good things for people. Who became good men.
But because we are rightly unequivocal about rape, I think we, as a society, find it hard to articulate complex but positive feelings about a rapist.
