Saul Alinsky is the Che Guevara of the USA. Before he died in 1972, he provided battle plans to the far left in the form of written "Rules for Radicals." It is said that Hillary Clinton wrote a paper at Wellesley College about Alinsky, but I have not been able to confirm that.
Alinsky laid out 11 strategies to destroy political opposition to the left. Rule number five is this: "Ridicule is man's most potent weapon. It's hard to counter-attack ridicule, and it infuriates the opposition, which then reacts to your advantage."
