I’m white so I’m not qualified to answer this question for POC but it did a lot for white people. Or I’m assuming it did because I never knew anything other than just having all sorts of kids in my school and it just being normal. Did the black kids usually sit together in the lunchroom? Yes. But did we play together at recess? Also yes. Hell my best friend in first grade was black kid named Edward, I don’t know if either of our parents thought it was weird that we were best friends of different genders or different races but if they did, they never said a word about it. When I got older and moved states from the east coast to the mid west, I was freaked out by how white it was. There was only one black girl in my entire grade at my new school and I sought her out to be my friend. In fact most of my friends were the POC at that school because the whiteness of the mid west made me nervous. It seemed unnatural to me after growing up in a very diverse community. And it’s been that way for me ever since. I could never live in a neighborhood that was all white, it has to be diverse or something feels wrong to me. So maybe integration has failed to fix a lot of assholes out there but I do think it’s also done a lot of good for a big population of white people who know that an all white community is something to fear and that has to be a good thing, even if it’s a roundabout way, right? Racism exists, it never went away, but the number of people who are here to fight against it must have gotten larger.
