Speak to any Zoomer &/or Gen-Z regardless of Race. All ( of Which tht are Neurotypical ) adopt Ebonics or All speak in Slang popularized by Blacks.
It really isn't a matter of IQ nor race js Cultural developments like the the progress of Rap ( Legitimately the No.1 Genre in America since the 00's or so )
Though, the Roots of Ebonics are butchered words since it comes from Enslaved West Africans trying to pronounce English Words w/ their West African Phonics.
Just like any Foreigner who decides to adopt English as a 1st Language. Especially one unfamiliar w/ our Phonics & w/ No formal education of English.
But It's beyond me why its perpetuated. The Black community should've evolved beyond this years ago. Around the 1930-60's If i'm not mistaken the Black community
was actually something to be respected. With the Harlem Reconnaissance, Civil Rights, MLK/Malcolm X, etc. The current generations just laid waste to their progress.
There just isn't anything redeemable about the Black Community as of Today.
