People who are liberals look upon the principles of Marxism as abstract dogma. They approve of Marxism, but are not prepared to practice it or to practice it in full; they are not prepared to replace their liberalism by Marxism. These people have their Marxism, but they have their liberalism as well - they talk Marxism but practice liberalism; they apply Marxism to others but liberalism to themselves. They keep both kind of goods in stock and find a use for each. This is how the minds of certain people work.
