I'd say it's a throwback from 60s (if not 40s.) The book is full of terminology and general attitude, that I found rather annoying. Is it leftist? Hmmm .... not really, just annoying. Bad, platitudinous humour, although the good thing is there's not much of it. Very deficient logic all over the place. Many connexions seem missing--I contstantly catch myself thinking, "and how did you get there from here?" No answer. There are some good thoughts though, and also historical data (especially on "non-violence" of people like Gandhi and Nehru.) I didn't know of these and found it all enlightening (although you will probably dislike the lessons that Mr Alinsky suggests can be learnt from these facts.) I'll probably read a couple of books that are quoted in this one, which makes reading this book already worth it. Finally, whether you like it or not, it's not a big book, so I'd say peruse it. Parts of it may be useful. At the same time, I don't share the overflowing enthousiasm of the other reviewers here.
