Fundamentally the political left cannot accept reality and observable truth. The real world doesn’t fit their preconceived ideas of how the world “should be.” They see the real world as broken and needing to be changed, ignoring the fact that their preconceived ideas on how the world “should be” may be what are broken.
Equality between sexes, races, geography, has never been observed and does not exist anywhere in the world today or in the history of the world. There is zero evidence of equality actually existing. The fact is, if you believe in evolution, then equality is not something you can justify. Evolution produces unequal outcomes, not better or worse outcomes but unequal outcomes.
Fact, people of east African descent disproportionately win marathons. Fact in USA, where blacks make up around 13% of the population, they comprise about 80% of the professional NBA players. Fact in the USA white people of Northern European Ancestry make up a disproportionate percentage of professional NHL players. Over the past 15 years a totally out of proportion percentage of American spelling bee winners have their ancestry in India. For generations the best design and manufacture of optical lenses come from Germany and Japan. Equality just doesn’t exist – PERIOD!
In the real world people can and do capitalize on their inequality. The left however desperately wants equality, even in absence of its existence. They see some people getting rich as proof of evil, not evidence of scientific fact that some people have different skills than others. The see some groups being more violent than others as evidence that they are being suppressed, rather than they have a different unequal culture that is more accepting of violence as a means of solving differences.
“The agenda of the left -- promoting envy and a sense of grievance, while making loud demands for "rights" to what other people have produced -- is a pattern that has been widespread in countries around the world.” ~ Thomas Sowell
The ideas of “equality” have been put to the test. The moral call for equality is a background for the political agenda of the left. This call for equality they claim will lift the poor out of poverty, end wars, and make the world a better place. This is the same claim that ruling oligarchies has made for centuries all around the world. It has also failed for centuries. Those nations which mandated equality, strictly controlled by ruling elite who knew best how to make things equal, are dead. From the French Revolution, to the Boxer Rebellion to the rise of the USSR and Communist China and the other ”equality” based societies created in history all resulted in the same outcome; mass starvation and mass murder.
Because the observable truth and history, clearly shows that equality does not exist, the left only use emotions to promote their failed ideas on how the world should be. If the preconceived idea of the left was right, then history would show that central planning by educated elites with the power of government to force their would have been more vastly more successful than economies based on individual liberty and free trade with millions of individuals pursued their own individual interests.
The radical idea that has proven to provide the most people with the highest standard of living is embracing inequality. Liberty results in unequal outcomes, but those outcomes are generally better for everybody. The only equality that should and can exist in culture is the idea that all people should be treated equally under the law; this is to prevent oppression, allowing all people to use the advantages they have by being unequal from their fellow man. This is an idea that is based on reality and observable truth.
The reality of people not being equal in IQ, disposition, drive, strength, speed, coordination, social skills, size, beauty, and all other capabilities, results in unequal outcomes in life. This isn't fair; to bad, life isn't fair. Because life's outcomes don’t fit with the emotional desires of how the left thinks things "should" be, they emotionally attack it leaving reason on logic behind. Human equality is a myth. I challenge you to prove me wrong by showing some scientific rationale to prove equality actually exists.
Tocqueville’s warned that equality is not a defense against tyranny, but an open invitation to ambitious and cunning leaders who enlist our support in depriving ourselves of freedom, saying:
"The…sole condition required in order to succeed in centralizing the supreme power in a democratic community is to love equality, or to get men to believe you love it. Thus the science of despotism, which was once so complex, is simplified, and reduced, as it were, to a single principle."
