In the 90's, a full grown man who was pretending to be a doctor, wrote a book called Men Are From Mars, and Women Are From Venus. The book simply stated that women are emotional, and men are rational, while writing about his downright abusive irrational treatment of his own wife, and somehow this was a best seller.
@RickiTarr It was part of the anti-feminist backlash of the era. There was a lot of smug gender-essentialist nonsense being pushed, with a thin veneer of liberalism. I saw that book as on a continuum with columnists mocking "metrosexuals" and lamenting the good old days when sexuality was mysterious, and with Camille Paglia getting interviewed fucking everywhere.
