Alinsky says to combat an enemy, identify it, freeze it, personalize it, demonize it, give it a person's name- (It's Bush's Fault for example).
If someone today says on Free Republic, “Barack Hussain Obama is a murtad fitri”, they can't do to the poster what they did to Joe the Plumber.
As soon as “Joe” was identified they were all over him. The “volunteers” in media and government dug up stuff in two days that the man himself did not know.
Remember how doggedly they worked to identify Buckhead and try to demonize him for being the first one to recognize the proportional fonts used in the Dan Rather memos National Guard memos.
