Could someone please translate that screed into white English?
I've been reading these kinds of screeds for fifty years. Certain blacks are upset that some white people imitate black music. Back in the old days, some blacks were upset that white musicians recorded music by black musicians.
For instance, a number of black musicians and afficianadoes were upset by whites who played jazz or blues. When the Beatles recorded a few songs by black musicians, some blacks accused the Beatles of "stealing" black music. As if The Beatles wouldn't have become famous if they hadn't recorded "Twist And Shout" by the Isley Brothers.
Some whites agreed and stated because of racism and slavery, whites should not play black music. Of course, whites were more than welcome to buy black music, and they didn't ask black musicians to stop playing white music....which many blacks did in those days. It was all hypocrisy and just as trivial and ultimately meaningless as this rant by this ignorant person.
It all comes down to the fact that a number of blacks are permanently angry. Nothing will make them happy. But they certainly don't mind enjoying the benefits of living in a country created by mostly white people as opposed to going back to the motherland and all its glories.
