The article’s writer, Jeet Heer, is obviously disliking of Heinlein’s politics and this impairs his ability to comment effectively. Really, the only wonderful pieces of the article are the direct quotes from Heinlein.
Face it Jeet, Heinlein started out as a left wing liberal and decided it was no good for a person or society. When liberalism move even more to the left, he declined to go with it.
