I'm with her on this. It's kinda Anglo-American prudish to be shocked, shocked about nudity. I prefer the continental European way of thinking about it, which is that it is kinda nothing and images can be what we call art if done thoughtfully. For comparison, see Greek athlete statues and Renaissance nudes.
And I don't have a quibble with her trying to sell her book. For me, the reporters who cook up these sorts of stories come across as obsessive (and nasty in the way Republicans wish to portray Dems) to denigrate everybody and everything in the orbit of Trump.
I wish her the best of luck with her book.
