rebels without a real cause

Just trying to understand the many protest marches throughout the world and I read this bit written by the great KG Chesterton. He wrote this in the early 1900s

"All denunciation implies a moral doctrine of some kind and the modern skeptic doubts not only the institution he denounces , but the doctrine by which he denounces it. Thus he writes a book complaining that imperial oppression insults the purity of women, and then writes another book, a novel inw hich he insultsit himself. As a polititian he will CRY OUT THAT WAR IS A WASTE OF LIFE, and then as a philosopher that all of life is a waste of time. A Russina pessimist will denounce a policeman for killing a peasant, and then prove by teh highest philosophical principles that the peasant ought to have killed himself. A man denounces marriage as a lie and then denounces aristocratic profligates for treating it as a lie.

The man of this school goes to a political meeting where he complains that savages are treated as if tehy were beasts. THen he takes his hat and umbrella and goes to a scientific meeting where he proves that they practically are beasts. In short, the modern revolutionist, being an infinite skeptic, is forever engaged in undermining his own mines. In his book on politics he attacks men for trampling on morality; in hsi book on ethics he attacks morality for trampling on men. Therefore teh modern man in revolt becomes practically useless for all purposes of revolt. By rebelling against everything he has lost his right to rebel against anything"
