What's are your thought on race relation in the us back then and now?

Thoughts, considering i am not a white person that i have about this is that back then it always have been differences that people of different races have thought of and because of that back then we were mostly divided into groups but as time progressed and history started taking more place now it is more like we are all together as one civilization and that makes me happy and relived that difference is no longer really a thing now. there might be a little bit of what we had back then but it is true that the problem is almost demolished.
