I read exactly what you said which was....
"You would actually struggle to find a lot of music that is of white origin to be honest. "
If by origin you mean directly influenced, and by your last comment that also means only going back to a single level (because jazz itself is highly influenced by European music , much more so than it's Afrian roots) then most of the music has little to do with Jazz or Blues.
I'm glad you resorted to an insult because it saves me having to bother having a decent a civilized discussion about the origins of modern music.
