Thing about Arnie: he used to be a sexist stinker, by every account I have heard, but when he was crossly accused about it in the end, he took a long hard look at his behaviour and really didn't like what he saw – so he apologised to the people he'd hurt, and changed the behaviour really quite a lot over a short space of time. I think he took an anti-harassment training course to make him aware of what he'd been doing wrong.... This, to me, makes him a lot less bad than he was before he "saw the light", realised how horrible he was being, and stopped. I don't suppose he managed it overnight, because people generally don't, but at least he tried, and seems eventually to have succeeded. And he seems to have been quite open about it all, too.
