Were these wolves "indoctrinated by nationalist propaganda" or is tribalistic behavior and in-group preference innate to most species on earth? Obviously the latter - I'll post studies on animal tribalism in this thread.

"In-group favoritism is widely observed in non-humans as well, ranging from primates to microbes." Red fire ants "kill others with different odor cues," side-blotched lizards with different morph colors engage in competitive mating.

Macaques "automatically distinguish the faces of members of their own social group from those in other groups [...] automatically evaluate ingroup members positively and outgroup members negatively" and "display greater vigilance toward outgroup members." pubmed.ncbi.nlm.nih.gov/21280966/

They also "spontaneously associate novel objects with specific social groups and display greater vigilance to objects associated with outgroup members." The study concluded tribalism is "rooted in phylogenetically ancient mechanisms."

(Some experiments from this study retracted, but the last two were confirmed)

R. Sapolsky, Left-Wing professor of neurobiology at Stanford, said "Primates are hard-wired for us/them dichotomies. Our brains detect them in less than 100 milliseconds. [...] 'us and them' is a fundamental fault line in our brains."

Capuchin monkeys are selectively kind and generous toward members of their own group: "Prosocial tendencies increased with social closeness, being lowest toward strangers and highest toward kin."

Perhaps the most infamous example of between-group competition among primates is the Gombe Chimpanzee War, a four-year conflict between two neighboring chimp tribes. One tribe defeated the other, massacred the males, and took their land. Sounds familiar...

2014 study recorded every chimp killing at every study site in Africa. It found that 60% of all chimp-on-chimp deaths were the result of male-driven between-group violence. One of the authors said "evidence suggests that chimpanzees just do this naturally" nature.com/articles/natur…

Honey ant colonies "defend spatiotemporal borders" & "access to temporal food sources" via elaborate display tournaments involving the largest ants, and "battles among ants can be startlingly similar to human military operations"

A 2020 study on chimps found that between-group competition enhances in-group cohesion; the more border patrols and tribal conflicts a chimp troop engages in, the more tightly-knit their community becomes. link.springer.com/article/10.100…

All evidence indicates that humans and other group-living animals are just "racist" by nature, and that being "racist" is evolutionarily adaptive. If tribalism were unnatural, libtards wouldn't use threats of jail, poverty, and violence to force people into being "anti-racist."

Are some people "anti-racist" by nature? Of course, they usually look like this and they didn't exist en masse before the industrial revolution:
