Unhappy Scientists are root cause for human annihilation!

It seems like deep thinknig unhappy scientists are root cause for hatred and racism. Strange how scientists were trying to prove their theories in the early days using humans, and now politicians are continueing their pligt. Those days these humans were called "wild beasts" and were displayed in human zoos, however today they are called terrorists and you must kill one when you spot one. Since i have this strong desire to put blame on someone, I would like to blame the scientists. I personally believe deep thinking, depressed scientists are root cause for human annihilation and we must save our earth from scientists.
Let me give some evidence for my thinking and let us hope i am not one of those deep thinking depressed scientist.
Human zoos, sometimes called "ethnographic exhibitions" or "Negro villages," were objects of anthropology and anthropometry and also an important means of bolstering "popular racism." Human zoos were popular from the 1870s until World War II, and the concept survived into the 21st century. Ethnographic zoos were often predicated on unilinealism and a version of SocialDarwinism. Many placed indigenous people (particularly Africans) in a continuum between Europeans and the non-human hominids.
Fundamental to scientific racism, unilinealism claimed Western culture was the contemporary pinnacle of social evolution. It was upheld by famous thinkers such as August Comte (1798–1857), Edward Burnett Tylor (1832–1917), Lewis Henry Morgan (1818–1881), and Herbert Spencer (1820–1903). Social evolutionism attempted to scientifically formalize social thinking, and was later influenced by the biological theory of evolution.
Displaying human beings in cages to demonstrate scientific racist theories was common in the second half of the 19th century. The 1889 World Fair in Paris had as major attraction a "Negro village" where 400 indigenous people were displayed. Carl Hagenbeck, a German merchant in wild animals, exhibited in 1874 Samoans and Sami people described as "purely natural" populations. Two years later, he sent an emissary to Sudan to capture wild beasts for his circus attractions, along with Nubians. Geoffroy de Saint-Hilaire, son of Edouard Geoffroy Saint-Hilaire and owner of the Parisian Jardin d'acclimatation, presented Nubians and Inuit in 1877.

I refuse to accept the view that mankind is so tragically bound to the starless midnight of racism and war that the bright daybreak of peace and brotherhood can never become a reality.... I believe that unarmed truth and unconditional love will have the final word. ~Martin Luther King, Jr.
