Haha, I know, they would!
The worst/craziest thing about the letters is how sweeeeeeeet and charming and kind and thoughtful sister Diana is, had to keep reminding self of the beliefs she was absolutely passionate about! Eg holocaust vv exaggerated, fascism really rather fun and kind.
The only thing that I was glad Diana Mitford was blisteringly honest about (on desert island discs etc) was how charming and charismatic she found hitler, because so many other accounts were a bit like, ‘ well obviously I knew there was something OFF about him from the first minute etc etc.’
The reality is that there must have been very attractive qualities about him to make him able to be such a pied piper of evil to so many, and we need to admit this so that we recognise it when we see it. But I’ve only ever heard Diana Mitford say it out loud. So many leaders, good and bad, lean heavily on their own charisma and charm to bring people along with them.
