I agree with a lot of this and it takes a discerning eye to figure things out like you do.

I think people need to simply credit where their styles came from as you say and we shouldn't be so ferociously cruel to people who might have good intentions but err.

I also don't think that all non-Black people today should shoulder the burdens of what happened to black people a long time ago, but you're right that some balance needs to be made about honoring those hardships.

I also think Elvis Prestley didn't live in the same climate where such things came under scrutiny. I also saw his original home in Tupelo, Mississippi and he was from a place of extreme poverty. I feel like a classist perspective might say that the music belonged to all of the poor people. I visited the Delta Blues Museum that I believe might be funded partially by Morgan Freeman which is one of the definitive cultural centers of black music and some of the pioneers in the blues were white as well. I feel like people of all races can lay claim to the development of this music. It's criminally simplistic to suggest that the evolution of music stops when it passes over from Black to White hands. and if it's a matter of privilege, no one in Mississippi playing the blues was ever rich or came from old money.
