Query: Sorry I didn't know Alinksy

After reading this book I'm sorry I didn't know Saul Alinsky. I love his sense of humor, his pragmatic situational ethics (which I presume President Obama learned from him), and his awareness that it is in one's self-interest to be your brother's keeper. The book is dated in some ways, but the general approach rings true. As he told his young colleagues who faced strong opposition in their attempts to get their country to live up to its democratic ideals: you can do one of three things: feel sorry for yourselves, start bombing (which will swing people more to the right), or you can organize.
