Transparency first
I'm a 52yo bald, bearded, speccy man (+ lone parent to 2 dds under 13, primary carer 100% residency). Progressive, Social justice & Vegetarian (one of the dds isn't). Yep, I rock the moby look I'm quite the fanboi. Still am, for the moment.
Moby, mate, you are so doing it wrong, I read the Guardian article. Man, you have got it so wrong. In a long rambling way let me explain.
In 2000, I was working in broadcast media in West London, actually I worked for three of the big players. We've been in the same building, I've even stopped you in the foyer to go "your music's great man - f4€king awesome", you went "yeh, Cheers thanks" in an utterly indifferent non committal way and I put my arm around your should and gave you a manly hug squeeze. You looked a bit wide eyed freaked and smiled it off. You know that moment in your life as a celebrity, when a fanboy gets too close for comfort - yeh that feeling. Hold on to that memory mate for the rest of this.
I'll freely admit, I've hit on women much younger, back when I didn't have responsibilities, There is that moment, as a man when your chatting to a 20 something and your in your 30s when you think, "Yeh I'll ask you out", but then as a self aware adult (not a celebrity) you read the change in temperature. What has gone from a pleasant conversation to an uncomfortable situation for the young woman, because I oversteped a boundary and she has to extracate herself with the minimum of bother. Believe me, Moby mate, we men are bothersome to women because they are unsure what level of manchild temper tantrum we will have.
you're having one right now, Ms. Portman is well within her rights to define the interaction as she sees fit, actually that under plays her rights. Respect how she feels about it, not how your ego wants the world to know about it.
Remember that feeling I asked you to hold on to. Now use that and mentally emitionalky switch places with Ms. Portman.
Please respect her and please introspect your role as a man in this.
Finally, on a separate note, when I was 18, I was having a moan to a nurse who was very feminist. She looked me in the eyes and said "You are a white man you have all the privelege in the world, you have nothing to worry about". Her world's have lived with me to this day. Maybe Moby consider what your privelege is doing right now and how to use it for the better.
