"Racist" is the constant epithet of the woketard left. Don't fall for it. The simple fact of the matter is that all people are racist. Everyone who has ever lived or will ever live is racist. It's a natural part of the human condition.  

 
From the wiki article, linked below:

 
"Kin selection is a process whereby natural selection favours a trait due to its positive effects on the reproductive success of an organism's relatives, even when at a cost to the organism's own survival and reproduction.[1] Kin selection can lead to the evolution of altruistic behaviour. It is related to inclusive fitness, which combines the number of offspring produced with the number an individual can ensure the production of by supporting others"

Let's put that in a way anyone can understand. You care about your own family more then you care about other people's families. This is why racism exists. People sacrifice for their own family while they would not sacrifice for others.

 
Kin Selection evolved because:
1) resources aren't limitless  
2) society depends upon altruism and  
3) outsiders can take advantage of that.  

 
And since human beings could not have survived without Kin Selection, and racism is the natural byproduct of Kin Selection, then on what basis is racism immoral? If we would have gone extinct without it, then it cannot be immoral. If someone tells you it's bad to be racist, then they're telling you it's wrong for you to love your own family.
