They're basically responsible for the majority of popular music. Without the blues, there would be no rock n roll, thus there would be no Beatles etc. Most of the music you love has black roots somewhere. The music they made from the 50s to the mid 80s was good BLACK music, now it's nothing more than disgusting, degenerate nigger music.
And can you think of a sporting icon more iconic than Muhammad Ali? Me neither.
If you can live without music and sport though, blacks are next to useless.
