We must listen to how the non-white people say stuff happens or works.
If we want to know about the ocean, we cannot only pay attention to the water, we also need to know about fish. If the water claims it is the perfect temperature, but all the fish are freezing- there is a problem.
When it comes to racism in America, we should listen to what the non-White people are saying. There are plenty of studies, plenty of lawsuits, and lots of stories about race and racism coming from White America. CRT turns this around and centers the stories and viewpoints coming from non-White Americans.
This is called counter story-telling.
So, if we pass a law making it illegal to segregate schools by race, and then all the White people move away from the school, CRT does not begin by asking the White people what is happening but rather listens to the Black students left at the school.
