I generally don't write a lot about politics on my blog, but I'll make an exception. John Holdren, Obama's new science czar, advocated some absolutely, monstrously evil policies back in the 1970s. Blogger Zombietime has scans of a book that he wrote with the infamously wrong-about-everything environmentalist Paul Ehrlich.
In the book, Holdren warns of ecological catastrophes sweeping the world by the year 2000 if aggressive population controls are not implemented. These include mandatory abortions for entire sectors of the human population, forced sterilization for undesirable people and, ultimately, complete government control over who can have children, how many, and when. This would be supervised by a worldwide government with absolute police powers.
This man's opinions should never be sought in any public policy discussion, at any time, now or ever.
