Cass Sunstein is a tremendous writer, in volume and in content. A law professor, he headed Obama's OMB office reviewing regulations during the first term. He's also married to Samantha Power, our UN Ambassador. So you figure he's firmly in the liberal camp.
He forfeits all that by his essay on "Gone With the Wind", the book, in the Atlantic.
I have to say I think I had much the same reaction 20 years or so ago when I read it. Mitchell told a good story, strongly feminist. As I say in a comment on the website, I'd compare it to Downton Abbey, a similar romantic gauze combined with stories and nods to the changing times.
