The author of the article is a very successful newspaper and media editor, most recently of the Daily Beast.  Also a recent biographer of Princess Diana, who saved Vanity Fair, in large part, by revealing the infidelity of the Prince of Wales.

However, since she laments "toxic testosterone" and the coarsest notion of "virility", as her wikipedia article relates - it's worth noting she had an affair with a married man 25 years.  

Sir Evans deserves the most blame, cheating on his wife for a younger woman - but TURNAOUT is fair play, bringing this up regarding this poseur of individual virtue.  "Crude interpretation of manhood" indeed.  She did marry him.

Lady Evans rightly calls out Trump's statements, but seems the type of feminist who sees misogyny and discrimination hiding behind every (non-liberal) bush.  Does she criticize Theresa May because she is "inept" or because Brown doesn't like her politics.  

My guess is Ms. Brown didn't care for Thatcher either, "ept" though she was.
