Consider the line above: "Often, the book is less about science than the people who explore and expand our horizons." My, oh my, how prophetic.
As unfolding events are demonstrating, Bailey's book seems to be more about his own midlife crisis and his own internal demons, and the ways in which they cause him to view every aspect of human motivation through the lens of sex - sex devoid of love, companionship, partnering or committment - than it is about scientific research regarding transsexual women.
Bailey does nothing to "expand our horizons" regarding transsexualism. Instead he merely gives us glimpses into and reflections of his own sexual thought-preoccupations - as he struggles to cope with his own sexuality while voyeuristically observing and then caricaturing the gender metamorphoses of transsexual women.
Barker IV's father is B. Devereux Barker III, of old-moneyed, Newport, Rhode Island, yachting fame. Here is a short bio for Barker III from the Encylopedia of Yacht Designers website.
"B. Devereux Barker III ~ Dev Barker was an editor at Yachting from 1962 - 1972 and edited the Design Section for five years. He's raced to Bermuda 12 times, ran an America's Cup in 1970 as chairman of the NYYC Race Committee, is on the Board of the American Sail Training Association, and a member of the America's Cup Hall of Fame Selection Committee. - - - "
Barker IV's hobby job is posturing as "Managing Partner" of the Wilson-Devereux enterprise, a company that has promoted all of twelve books (wow). Hope this gives you some idea of the sort of character who is now heavily into promoting Bailey's "Transphobia for Dummies".
