I heard GG speak in person a few weeks ago. I wanted to hear her in context, because so often all we hear of her is a controversial sound bite.
She was speaking on consent (and an interesting article on the topic on Feminist Current atm, not by Greer). I didn't think she had lost the plot. She is unorthodox; she is also a rape survivor herself, which gives her more right to comment than I do.
I think she expressed very clearly the corrosive nature of bad relationships. Her view is that men in long term relationships can do as much damage to a woman as rape by a stranger.
For someone who is anti marriage, never had kids, I feel she has a lot of compassion for those of us who do, and who struggle with our relationships with our male partners.
I also think she is quite tired. She commented more than once that she is getting old. She finds solace and instruction in poetry, apparently.
It's not possible to agree with all things Germaine. She's said some stuff I've raised an eyebrow at, and more. But she is a brilliant woman, and - I felt upon seeing and hearing from her - ultimately a compassionate woman, especially but not only towards women and children.
I'd encourage people to read her essay On Rape, because I think GG is always better in full context.
