I think this might just be a consequence of extremely homogeneous society/ cultures. America being so diverse would likely be less racist than an extremely homogeneous society irrespective of how much attention they actually put on race.
In what ways do you think this obsession manifests? Could you give examples of what the American obsession with race looks like on a behavioural level? >

Diversity courses for jobs, the actual acknowledgment of slavery, and of course media obcession with racial incidents from police shootings to  subliminal Karen type discrimination >


Diversity courses for jobs, the actual acknowledgment of slavery

Do you really think these are what people are referring to when they talk about an obsession with race?

media obcession with racial incidents from police shootings

This is getting closer... >

Some people, absolutely! >

Imagine raising a group a children of different races in seclusion and making no mention of race. They would treat skin color like hair color and never have a racist thought. However, thanks in part to social media, people can now make a lot of money by trying to hyper focus on race and tear people apart. >

Naa, racism is only possible by whites. Twitter told me so >

Constantly talking about racism is keeping racism alive.
Granted, the USA is one of the few melting pots.  So, we have to confront race issues.
Much of the world is still very homogenous.  Norway surely has a larger white majority than we do.  And most people in Japan are Asian.  Most people in Latin America are Hispanic or Mulatto.  And most people in central Africa are black.  (Although, let's not forget that the Rwanda genocide was one ethnic group of black folks killing another ethnic group of black people.)
Out of curiosity, how are Australians, New Zealanders, and Canadians handling relations with the aboriginal peoples? >

Latin America is actually more diverse then the United States. Brazil for example is half black or Pardo. And effects of colonialism/ Slavery is only minimally addressed.
Canada handles indigenous relations better then America imo. They even use the term first nations to describe them 
Australia follows more of the UKs model which is to largely pretend nothing happened >

The thing about Canada is that its all words and no action. Justin Trudeau likes to pretend he's trying to right the wrongs of the past, but in reality, hes capitalizing on the suffering of a people who have suffered enough. Manipulating peoples empathy for electoral gain. Have you ever seen a canadian reserve? Especially ones in northern Manitoba and Saskatchewan? Theyre not getting better, not even close.
