she's hardly had a personality change. You just disagree with her on this specific matter.
Well given that her books have oft been quoted to highlight the lunacy of all this, and now she’s saying something that seems wholly contradictory to her writing, it feels like a personality change to her readers.
Maybe she never really believed there was any real world inspiration for the way people were segregated in the Handmaids Tale - it was all just pure imagination and whimsy, with no factual basis in any form of sex-based oppression. Just pure coincidence that women’s reproductive labour was being explored I expect.
It’s definitely amazing that most, if not all, of her readers seem to have seen something in her writing that she apparently didn’t intend though.
If only the Handmaids had realised that all they had to do was to identify their way out of their situation by claiming to be at the Commander end of the spectrum, they could have saved themselves a load of heartache!
