The Left is the most dangerous ideological phenomenon in the history of mankind. It glorifies poverty, the total state, and mass death. The Left wants to destroy Western civilization, based on Christianity, the traditional family, and the free market.
It's no coincidence that Communists killed more than 100 million people, not including their wars.
By the way, young people are not taught about the evils of the Left, only its myths. They do not believe there were gigantic atrocities in the Lenin-Stalin Soviet Union, nor Mao's China. Socialism is good! Everyone is better off under socialism. Everyone is Equal.
Equality is the magic word. Since it does not and cannot exist, it is is a license for total state power. After all, some people are smart, some stupid. Some good looking, some ugly. Some creative, some dull. Some hard working, some lazy. Some athletic, some couch potatoes.
According to the Left, private property and the free market are evil, not the sources of prosperity and civilization itself. The family is the ultimate evil, since is the ultimate source of inequality. That's why Karl Marx called for its abolition.
The key fact about the human race is our radical inequality, said Mises. Without it, there could be no division of labor, no social cooperation, no market. There could be no liberty, because liberty depends on the ability of people to exercise without hindrance their unequal talents.
It's more than ironic that Leftists call us fascists and Nazis, since fascism had its origins in communism and socialism, and Nazism was National Socialism. Both Mussolini and Hitler denounced the free market and all it stands for. But then, Leftists never tell the truth.
Where did this poison originate? Not so much in the ancient world, though it had its advocates there too. One Greek myth talked about the ruler Procrustes, who would force visitors to sleep in his iron bedstead. If you were too tall, he'd have your feet chopped off. If too short, he'd have you stretched on the rack. It's still a good summary of egalitarianism.
The birth of modern Leftism was the French Revolution, with its wars, conscription, egalitarianism, mass deaths, and total state. Defeated, it rose again in Communist Marxism, the Russian Revolution, and all its despicable offspring.
