No, Diversity Is Not the Cause of Violence

On December 13, 2025, a man with a gun killed two students in a classroom at Brown University and left half a dozen seriously injured. This tragedy did not make headlines around the world because shootings are a tradition in the United States. According to various statistics, for a century (it would be necessary to add the colonization of centuries before, carried out by religious fanatics against Indians, Blacks, and Mexicans), mass murderers have tended to be supporters of the supremacist right, but it is they who blame diversity for all the ills of their societies. Fear is big business.

This massacre took a back seat when, the following day, 11 people were killed in Sydney, Australia. The victims were members of a Jewish community celebrating Hanukkah. Since the ban on semi-automatic rifles and strict regulation of firearms in 1996, massacres in Australia are a rarity.

Immediately, social media was flooded with explanations about the danger of Islam to the world, even when it was revealed that the man who stopped and disarmed one of the two attackers in the midst of the massacre was a 43-year-old Muslim, father of two children, who was shot twice. Benjamin Netanyahu will probably honor him with the Israel Prize in Human Values and Civil Heroism.

A couple of hours later, the richest Argentine in the world and resident of Uruguay, Marcos Galperin, who presents himself as the “founder and executive chairman of Mercado Libre” and Konex Prize winner, commented on the massacre with the same prejudice that the killers surely share: “Welcome to the new multicultural and diverse Australia.”

The now demonized multiculturalism is as old as the domestication of fire.

Could it be that the problem perceived by those who are against diversity is skin color? Why are non-Caucasians always the problem? When, for centuries, white people devoted themselves to assaulting, destroying, and massacring the rest of the world, they were only bringing civilization to those “shithole countries,” to use President Donald Trump's language to refer to the countries of the South. “Why do we accept people from these shithole countries, like Somalia, and not accept people from Norway, Sweden, or Denmark?” Perhaps because, to them, we are the shithole country.

The common factor is always the same: The problem is not cultural diversity, but something as superficial as skin color. When they find out that the native British and Belgians were black-skinned people, their blood sugar rises.

The now demonized multiculturalism is as old as the domestication of fire. There was no trade, let alone free trade (an ancient activity until it was destroyed by capitalism), without cultural, linguistic, religious, and technological exchange. From the 10th century until the beginning of the European slave trade, the Kingdom of Nri achieved almost 1,000 years of coexistence based on the principles of “peace, truth, and harmony.” The Nri culture, located in what is now
