I finished this book a few nights back. While I had a quibble or three, I found the book quite informative. One point it stamped into my gray matter is that the eugenic, birth control and euthanasia movements have been closely allied. Another is that the euthanasia movement is riven into factions, some supporting only passive euthanasia (withdrawing feeding tubes, e.g.), some supporting active euthanasia (administering a lethal injection to expedite death, e.g.), and some supporting not only active euthanasia but active euthanasia of unwilling humans.
