There's no such thing. This and other accompanying scientific facts were clearly established during the last presidential election:
"And of course a racist in Ireland would want to retake the North. That's what Racists are: Illogical. If a White racist went to a Black Supremacist meeting, they would be forced by their primitive, hive-thinking brains to instantly become Black Supremacists due to their environment, so they are driven apart by fear of being converted in front of their racist peers*, when, in reality, racists of seemingly diametrically opposed opinions find themselves believing the same things and hitting it off rather well, because they receive the closest thing their central nervous system that controls their otherwise normal-looking imitations of sapient bodies can produce to a Happiness hormone from meeting a creature as equally stupid as they. As such, you have inherited racism against anthropomorphic animals due to your environment after having been encouraged by the non-racist beings around you, and are driven away from me specifically by your fears.
*This is untrue for only a few exceptions, notably the newer, rarer species of Racist known as 'Weeaboo', or any other varieties aimed toward other countries. Due to birth defects worse than the ones already necessary for Racists to form, (Likely from mutant genes caused by racist inbreeding) these ones possess assimilation reflexes that work the exact opposite way that normal racists do, and they will consider any culture in present company to be inferior compared to another culture they have not experienced yet."
-Silas Schock, Racist Hunter.
"Racists are not a people. They're a disease attempting to be a larger animal. You see, racism is not a choice. It never is. No actual person, human or otherwise, is capable of such levels of blatant ignorance. When eggs are fertilized, sometimes, unfortunately, a certain variety of micro-tapeworm invades the developing fetus and it becomes a racist, like you, spending the rest of its life trying to imitate human behavior in order to receive food and dopamine for its consumption. As a racist in Ireland, you are driven to conquer North Ireland because that's what racists in Ireland do. As a racist here, you are driven to disgust by all Warrior Cats under any circumstances because this feature has been assimilated to you. In fact, it's rather ridiculous trying to argue this point because racists rarely know or admit that they are a symbiotic hellspawn, but it won't fix that much either way. Just keep your hands off any pregnant women you come across and I'll try to keep you from breaking too many things on the off chance you win the presidency, foul monster."

"Evil is a choice, most of the time, but I've squeezed enough racist innards to know that they are pitiful creatures infected with parasites before their birth. You've never killed one, nor could you recognize an inhuman husk if it bit you on the arm and you had to saw it off because slime tendrils started spewing out of the wound, so your opinion on the subject is irrelevant. Besides, as someone who's seen "The Leprechaun" in its abhorrent entirety, I'd like to think I know what real Irish-targetting racism looks like."
-Head Chef of Cystia shares his personal encounters with Racism.
"Racists are inhuman monsters, and a great many of them should be killed for the problems they cause. Humanity almost became a zombified race during the outbreak of the 16th and 17th centuries. The day that Abraham Lincoln started having them killed was a miraculous one. They are parasitically possessed, empty husks that have never been human, and can only be cured through very expensive, time-consuming surgeries whose resources shouldn't be wasted on empty-hearted monsters."
-A Site Historian explains the history of Racism.
"Nonsense. Racism, as I have come to learn from viewing /pol/, the definitive source of all information on racists, has a very distinct set of hypocritical beliefs. All Racists must want to conquer the North, because racism entails:
The hatred of all women.
The hatred of all men.
The belief that the Irish must conquer North Ireland.
The belief that the Scots must conquer Scotland.
The belief that England should tell both previous conquerors to go fuck themselves and rebuild the empire.
The belief that the French should rebuild the empire of Napoleon.
The belief that the Germans should conquer Everything.
The belief that the Italians should rebuild Rome.
The belief that the Turkish should Rebuild the Ottoman Empire.
The belief that Africa should unite and conquer the dirty Europeans.
The belief that Japan has the only good women and the only good video games.
The belief that everyone darker than a peach crayon must die.
The belief that everyone lighter than a peach crayon must die.
The belief that Asia should be burned to the ground, especially the Japanese.
The belief that the Middle East should be burned to the ground, especially the Turks.
The belief that Africa be burned to the ground, especially the Africans.
The belief that all of the Mediterranean should be burned to the ground, especially the Italians.
The belief that all of mainland Europe be burned to the ground, especially the Germans. And the French.
The belief that all Palestinians should die.
The belief that all Jews should die.
The belief that China and its inhabitants are inherently evil.
The belief that furries should all die/are inherently wrong.
Clearly, racism is a self-destructive force that only seeks the death of all sapient life, and it should be destroyed."
