There are white people on the east coast of Canada that I barely understand due to their accent and local vocab. There are people in the UK that speak in cockney which is essentially a language unto itself.
But we never say they speak "white". We just accept they speak differently. Could be geographic. Could be economic. Could be cultural. Regardless, it's just different.
Ebonics (regardless of what you're learning on Wikipedia) is not exclusive or limit to blacks. White, Asians, etc., adopt it as well.
The number of black people that speak "Ebonics" is a miniscule fraction compared to everyone else that speak just as "white" as you.
But again... It's not white, it's just familiar.
Maybe go make a black friend or two. You'll be disappointed to know they're just the same as all your white friends
