Geremia, who the hell is Saul Alinsky? Honest question. I only hear about him from conservative sources.
Read Clinton's thesis (at least the first third of it, or so). She does a very good job introducing who he is and how he used the Catholic communities of Chicago for his "community organizing" (i.e., Marxist) ends.
Alinsky was a Chicagoan son of an Orthoducks Jєωιѕн family; he dedicated his book
Rules for Radicals (1971) to "Lucifer, the first revolutionary." When asked if he believes there is life after death (the afterlife), he replied that the better question to ask is: "Is there life after birth?" ("life after birth" is the title of one of the sections of Clinton's thesis).
Another interesting aspect of the thesis is that she explicitly realizes Alinsky supports moral relativism. And she thinks being anti-private property isn't radical!
