Liberals vs. Radicals according to Alinsky

From Saul Alinsky’s book Reveille for Radicals (pg. 21-22):

“Liberals fear power or its application.… They talk glibly of people lifting themselves by their own bootstraps but fail to realize that nothing can be lifted except through power…. Radicals precipitate the social crisis by action — by using power…. Liberals protest; radicals rebel. Liberals become indignant; radicals become fighting mad and go into action. Liberals do not modify their personal lives[,] and what they give to a cause is a small part of their lives; radicals give themselves to the cause. Liberals give and take oral arguments; radicals give and take the hard, dirty, bitter way of life.”
